Paving stones on concrete technology. Laying paving slabs on concrete: choice of material, installation instructions. Criteria for choosing high-quality paving slabs

Laying paving slabs on concrete base is performed according to a special algorithm. If you strictly adhere to the recommended installation technology, you are guaranteed a reliable and high-strength coating for areas with heavy traffic.

In recent years, the owners of suburban areas are increasingly paving paths on the territory of their summer cottages with paving slabs (this material is often called paving stones). In terms of its strength indicators, it is in no way inferior to asphalt and concrete pavements, and in purely aesthetic characteristics it is much superior to them. Laying tiles on concrete is carried out using a special technology, which is considered quite complex and time consuming. But it is quite possible to implement it with your own hands. You just need to thoroughly understand the features of the concrete base and the rules for arranging paving stones on it.

Concrete base for laying tiles

It is important to remember a few points here. First of all, the concrete base must be a perfectly leveled area, designed for laying the tiles of interest to us. This method of installing paving stones guarantees a truly strong and durable coating. The key advantage of a concrete base is its maximum stability. In this characteristic, the concrete base differs for the better from the soil base and sand-crushed stone cushions. The latter, under the influence of the weather, can sag (and very noticeably), as a result pulling the paving slabs behind them.

Such deplorable situations do not happen if the paving stones are laid on a flat concrete area. Even under severe mechanical stress, the tiles will not sag. Thanks to this, you can lay paths with straight and curved shapes without worrying that they will change their configuration over time. Do-it-yourself installation technology of paving stones on concrete requires the creation of a high-quality water drainage system from the surface of the finishing material we are considering. For these purposes, point moisture receivers should be installed, storm drains should be laid, and tiles should be placed with some slope in a certain direction.

If you follow the specified rules for installing paving stones on concrete, you will not have any problems with the coating for many decades. Paving slabs paved paths will delight you with their durability and perfect appearance.

The described method of laying tiles requires careful preparation of the paving site. You need to split the site according to the given project, set pegs along the borders and set the so-called red marks. As such, professionals understand a thread (well stretched between the pegs), indicating the height of the platform being equipped. Putting red marks with your own hands is easy. You just need to tie the twine to the pegs at the height at which the paving stone will end. Here it is important not to forget about the five-degree slope of the thread to the place where you will subsequently install the water receivers.

Layout of the site before laying the tiles

Note! Height marks should also be set in situations where it is planned to lay tracks with a small width.In this case, the red thread provides:

flawlessly leveled horizontal surface;
smooth tile edge;
the desired slope of the gutters.

After setting the red marks, you need to measure the free space between the soil and the thread. If the distance between them is less than 0.3 m, you will have to remove the excess earth with a shovel, having received a pit suitable for laying. The builders call it a trough. It is advisable to strengthen the edges of the pit made with curbs. Experienced craftsmen put them after filling the earthen trough with concrete mixture. But for home craftsmen, this technology is usually not suitable. It requires the construction of plank formwork, the task of which is to protect the edge of the paving site from shedding the soil. It is rather long and difficult to build a formwork structure. For this reason, it is better for self-taught craftsmen to mount curbs right away.

The curb in its height should be slightly lower than the surface of the paving slabs. Then moisture will not stagnate on the paved area, but will drain from it. Usually, 0.5 m high curbs are used for laying paving stones in dachas. For those who plan to work with such products, we give a simple way of their competent installation. The scheme of work is as follows:

Deepen the pit by another 0.3 m.
Fill the bottom of the trench with a 10-centimeter layer of rubble.
Fill the hole with cement mortar (layer height - 1.5–2.5 cm).
Install the curb on the cement fill.

Now you should wait about a day, and then feel free to start pouring concrete. More on this later.

When arranging an ordinary pedestrian area, it is advisable to lay out a small layer of sand (up to 10 cm thick) on the bottom of the pit. It will function as additional drainage. And the main drainage system is made by creating special holes. Drainage in this case is made from pieces of asbestos pipe. The height of these pieces is within 0.15–0.2 m (it must necessarily coincide with the depth of the poured concrete layer). Simply cut the desired number of pieces from the solid asbestos pipe. And then spread them around the area. One piece of tubular is required for one square of area.

Then proceed to pouring the concrete mixture. It is made from sand, cement and crushed stone (the ratio of elements is 3: 1: 2). After pouring, there is no need to remove the pipe pieces. Concrete will harden for about 2-3 days. You can rest during this time and gain strength before carrying out the main operation - directly laying paving stones. If you are equipping a pedestrian path in your suburban area, there is no need to reinforce the concrete base. If you are pouring a paving site, on which large-sized vehicles will regularly ride, it is advisable to additionally strengthen the concrete base. To do this, use the simple method described below.

Pouring concrete

Reinforcement is carried out with metal rods of small thickness. They must be tied into a single structure with cells of 20x20 or 15x15 cm. When using reinforcing elements, pouring is carried out in two stages. First, make one layer of concrete. Lay a metal mesh on it. And from above, pour the concrete mixture again.

If you did all the preparatory operations correctly, you will not have any difficulties with installing paving stones on a concrete base. In most cases, tiles are laid from the border. It is advisable to mount the tiles in the direction of the water flow (from top to bottom), focusing on the exposed marks. Experienced technicians often lay the first items on the most visible side of the site. In this case, the paving surface is visually completely perfect, since the fit of the tiles and all their cuts remain in the most inconspicuous places. But this method causes many problems for novice craftsmen. Therefore, it is best not to use it if your paving experience is minimal.

Laying paving slabs

The paving stones are placed with gaps (4–5 mm), and not end-to-end. This is not done just like that. The presence of gaps protects the paving slabs from cracking caused by moisture and temperature extremes. Each tile laid must be leveled using a rubber mallet. Just tap on the surface of the paving stones and do not forget to constantly check the horizontalness of the surface to be mounted with a level. After laying all the tiles, the resulting surface is pressed down with a vibrating plate. The seams between the products should be filled with fine fractions. Pour it onto the site, sweep it with a broom into the gaps. And sweep the excess sand from the paving stones.

You have completed the installation of paving slabs on concrete. Congratulations!

Traditional sand and crushed stone base for laying paving slabs often gives uneven shrinkage. Especially if the laying technology was violated. Therefore, if the task is to obtain reliable and durable paving, they use the laying of paving slabs on a freshly poured or already existing solidified concrete base.

Laying tiles on concrete

Due to the fact that one of the "harmful" features of paving slabs lying on a concrete base is the danger of slow drainage of water, the frost resistance of the acquired paving stones must be at least F100-F200.

It is also very important what kind of mechanical load the purchased tile can withstand. Usually, this technology paving is used for the construction of highly loaded sites, therefore, the compressive strength of paving slabs should be within 50 MPa (500 kg / cm2).

Stages of laying technology

There are two ways to mount elements on a concrete base: on a fresh mortar and on an old concrete surface. Consider these two methods in more detail.

Laying tiles on fresh grout

After marking the site, go along the path along the edges to install curb stones. To do this, dig a trench with a width of "curb thickness + 2 cm, one centimeter of width per side." The depth of the trench corresponds to the aboveground and underground part of the curb, and the thickness of the cement-sand cushion (4-5 cm) is also taken into account for better fixation and leveling. For example, for a curb with a height of 25 cm, you will need to open a trench 10 cm deep + 4 cm (under the pillow) \u003d 14 cm.Further, the trench is filled with a cement-sand mortar prepared in a ratio of 1: 3 (1 share of M500 cement, 3 parts of sifted sand), after why curb stones are driven into it with a rubber hammer.
The space between the curbs is covered with a small layer (3 cm) of gravel or screenings.
On a small area of \u200b\u200bthe future site, a cement-sand screed prepared in a ratio of 1: 4 (1 share of M500 cement, 4 parts of sifted sand) is poured onto a layer of crushed stone 4-5 cm thick. Important! The freshly poured screed is leveled with the rule in the same way so that a slope of 2-3 degrees is obtained in the direction of water drainage. Immediately, not allowing the solution to "grab" on it, maintaining the minimum gaps, paving slabs are laid. Next, the next portion of the screed is poured and the process is repeated.
Laying of tiles is carried out using the technology "from oneself". In other words, the master, performing the work, moves forward along the already laid tiles;
Seams between the paving stones and curbs are sealed with the same mortar or dry cement-sand mixture. In the latter case, the seams are abundantly moistened with water.

Laying tiles on an old concrete base

This option is not the best in terms of aesthetics. If in the first option there is a possibility of building the site flush with the soil level or slightly, slightly above the soil level, then in this case the site will rise to the full thickness of the tile, and nothing can be done about it.

The concrete surface is thoroughly cleaned of dirt and dust and covered with a special primer for better adhesive adhesion;
The tiles are pre-laid out on the site. It is trimmed or cut out where necessary.
Part of the tile is dismantled. A special glue is applied to the concrete surface (sold in the retail network as a dry mix). A “portion” of tiles is laid on the glue, keeping the minimum gaps (you can use special plastic "crosses");
The procedure is performed "step by step" until the entire area or lane is filled;
The seams are closed as in the previous case;
The surface of the site is cleaned.

Advantages and disadvantages

There are two main advantages: longer service life and the ability to drive around the sites in cars or other vehicles;
The disadvantages include: higher cost of work, the need to arrange slopes and reliable drainage of rain and melt water.

Advantages of laying paving slabs on a concrete base

Sand and gravel substrates can often shrink. It is not suitable in cases where it is necessary to make a blind area of \u200b\u200ba building or a parking lot, therefore, when the most reliable and high-quality paving is required, laying paving slabs on a concrete base is more relevant. This design is capable of withstanding significant loads and long service life.

Advantages and disadvantages

Tile selection

First of all, you should pay attention to the frost resistance of the paving stones - it should be within the range of F100 ÷ F200. It is equally important how much weight the coating can withstand, that is, the ultimate compressive strength (50 MPa is recommended). Pay attention to the absence of chips at the edges of the tiles, you should also refuse to buy if the structure of the product is porous.

In order for each tile to be laid securely and evenly on the concrete base - depressions, protrusions and other irregularities are unacceptable.

An overly saturated, bright or uneven color often indicates a violation of the dyeing technology and, as a result, insufficient strength of the products.

Work stages

The decision to lay paving slabs on concrete can be dictated both by the need to restore the previous coating, and by the desire to update the existing design, while it is not necessary to engage in preliminary restoration of the old base. To lay out the garden path with paving slabs on the mortar, you need:

along the edges to install curbs (they will require depressions filled with compacted rubble);
over a short distance on the gravel (or the remaining wet concrete base), pour a cement-sand screed in a ratio of 1: 4 and about 3 cm thick, level it as a rule and immediately, without allowing the solution to set, lay the tiles, leave the gaps minimal. Pour a new portion of the screed and repeat everything until it is completely laid over the entire area of \u200b\u200bthe track;
seal the seams between the paving stones with mortar or grout, if they hit the front surface of the path, remove it before it hardens.

Sometimes an idea may arise to update the old concrete coating in the garage with the help of paving slabs, although the idea is not the best: over time, it will not be possible to avoid traces of oils, antifreeze and other liquids. In addition, the entrance will have to be adjusted as the surface level rises. But, if the decision is made, then the technology of laying tiles in the garage for glue is as follows:

the concrete surface is thoroughly cleaned of dirt and dust;
for better adhesion, the screed is primed;
the tiles are laid out on the floor of the garage, in order to eliminate inaccuracies and errors, cut in advance (if necessary);
some of the tiles are removed, glue is applied to the concrete (both ready-made and in the form of a dry mixture are on sale, the latter must be diluted, as indicated on the package) and laying is done. Plastic crosses are installed to maintain the same minimum clearances. The procedure is repeated until the entire garage floor is filled;
seams are rubbed, the surface is cleaned.

Pros and cons and cons of a concrete base

The first should include the fact that the coating is able to withstand loads more than on a conventional substrate. The concrete base gives you confidence that the tiles will not sag, and the service life is significantly increased. The disadvantage is that when laying in the open air, a slope of 2-3 degrees is required to ensure water drainage in case of precipitation.

If we are talking about updating the old base, the costs of which are no longer taken into account, then the "minuses" will have to include the price of laying on a concrete screed. Preparing a solid base, which itself is a coating, and then placing paving stones on top of it is relatively expensive.

DIY styling

Masonry is not so difficult to do that it cannot be done on your own. To put paving slabs 4 cm on concrete with your own hands, you will need:

at the edges of the screed, install a limiting formwork or lay curbs;
prepare sand-cement mortar 4: 1;
after wetting the screed, distribute the locked mortar in such a way that the required slope is observed;
lay the tiles, maintaining minimum gaps between them and adjusting their correct position with a rubber hammer;
place trimmed elements in the proper places last;
promptly clean the front surface of the tiles from the solution;
after finishing the installation, grout the joints.

The cost

The price of laying on a concrete screed, as a rule, is higher than on other types of bases, this is explained by the additional costs of its manufacture and the need to provide a slope, additional drainage systems. The estimated cost for work in Moscow is shown in the table:

Company	Types of jobs	Price, rub / m2	Notes

Step-by-step laying of paving slabs on a concrete base

Our distant ancestors invented to lay out streets and roads with paving stones, however, paving slabs appeared on the construction market relatively recently. Natural stone today has a rather high cost, but tiles made of pressed, baked clay, sand and other components will cost several times cheaper, which is why many consumers prefer it.

There are several fairly simple methods on how to lay paving slabs: on a concrete base, as well as on a cushion of sand and gravel. In the second case, it will be much faster, but such a coating simply will not withstand a heavy load, but in the first option, you can drive a heavy truck along such a path if you wish. Let's figure out together how to put paving slabs on a concrete base so that it will serve you faithfully for many years.

Process features: measurements, calculations and selection of materials

For a beginner, laying paving slabs on a concrete base may seem overly complicated, therefore many abandon this idea, preferring ordinary paths sprinkled with sand. However, such a coating cannot in any way be compared with paving slabs in terms of durability, strength, endurance, and indeed appearance such a tile is really great. So how to put paving slabs on concrete, what do you need to know and remember for this, and what nuances need to be taken into account?

The most important thing when it comes to laying paving slabs on concrete on the street is to organize the correct and competent removal of moisture, otherwise the winter cold will simply spoil your coating, if it is not washed away by torrential autumn rains even earlier. Drainage should be provided at least every three meters of the concrete screed. It is also necessary to take care of the slope so that the water immediately flows off the path, and does not stand there.

Marking and measurements

First of all, you need to mark the site, correctly measuring the area, the location of future paths and paved paths. The easiest way is to lay paving slabs on an old concrete path, which has been in operation for a long time, but if you wish, you can pour in a fresh screed, however, you will have to wait until the mixture dries thoroughly, since it is strictly not recommended to lay the tiles earlier. For beginners, it is better to abandon bent lines, creases and corners, since then you will need to devote a lot of time to trimming the tiles, and this is a tedious and painstaking process.

To correctly mark the territory and mark the boundaries of the paths, the easiest way is to drive in the pegs and pull a string between them. This way you will get an overall picture, which can already be assessed visually, and, if necessary, make some adjustments to the plan by making the tracks narrower or wider, longer or shorter. The most simple styling paving slabs on concrete means drawing up a plan or drawing, applying all sizes to it, so it will be much easier for you to navigate the necessary materials and raw materials.

Level when laying paving slabs on an old concrete base

Do not forget also about the level of the alleged paths paved with paving slabs. First, as we have already said, we should never forget about the slope, which should be directed towards the street, lawn or lawn, but not towards the house. Secondly, you should first mark where the curbs will be dug in, which are best to be thoroughly concreted, since they can slightly "walk" when the soil subsides, but the appearance, this can seriously spoil, and the integrity of the coating can be violated.

Also, first, if there is no old path, and you are just going to fill the screed, it is worth removing the layer of fertile soil completely, not less than 15-30 centimeters, and also remove all roots and stones. The path should not protrude above the lawn, as this can not only damage the surface, but it can also be inconvenient and dangerous due to height differences.

Correct tile and quantity

Thus, to the question of whether it is possible to lay paving slabs on a concrete base, the answer is affirmative, it remains only to find out how to choose the right materials and raw materials for its laying, as well as in what quantity the tiles should be purchased. With regard to the main characteristics and indicators, the first thing to look at is the thickness.

Photos from the site: Remoo.RU

The thicker such a tile, the more durable and reliable your coating will be, and it will be able to withstand much more serious loads for a longer time.
Immediately upon purchase, you should find out the frost resistance of materials, because in our climate this is extremely important.
When calculating the amount of material, you need to correctly measure all the areas of the tracks. In order for you to have enough for cutting, you should add another 10-15 percent to the resulting amount, then there will be no problems.
Curbs for laying paving slabs on concrete are sold, therefore, and are calculated in linear meters. It is worth measuring the entire length, and then throwing in three or four additional elements, which will also be used for trimming and in reserve.

Thus, we not only found out whether it is possible to lay paving slabs on concrete, but also learned how to correctly calculate the required amount of materials and raw materials.

Equipment, materials and tools

Experienced craftsmen-tilers and tilers know very well in advance what is required in order to lay paving slabs on concrete, but for a beginner this may be a complete surprise. It is worth dwelling in more detail on this issue, because in addition to the paving slabs themselves, as well as the border to it, additional tools and raw materials will be required.

Photos from the site: 1PoKirpichy.ru

If the screed is already available, and this is a topic for a whole separate article, then we will not talk about crushed stone and coarse sand, but ordinary, washed river sand will be required in order to lay paving slabs on concrete in a fairly large amount.
You will also need to purchase quite a lot of cement, M500 or M400 brands. You can take a cheaper one, but the quality then decreases significantly. Pay attention to the expiration date of this material, it should be produced no more than three months ago, as in the future cement increasingly loses its unique properties and qualities.
For the drainage layer, crushed stone with a fine fraction, no more than forty millimeters, will be required.
A construction level, a trowel, as a rule, a ruler and a shovel, work gloves, a pick, a hammer and a square, a cord and pegs to it - almost every home craftsman has all this.
If the area of \u200b\u200blaying paving slabs on a concrete base, as shown in the video at the end of the article, is quite large, it does not hurt to rent or even purchase a concrete mixer.
Manual, as well as mechanical and special rammers are also required to have on hand. It makes no sense to buy such expensive equipment if you are not going to use it for work, but it is quite possible to rent it.
There is no substitute for a special rubber mallet for leveling and tamping paving slabs, so you should buy one. Such hammers can be of different weights and sizes, it is worth picking up something in between, not very heavy, but also not quite light.

For cutting tiles to size in the corners and along the edges of the path, it also does not hurt to prepare a grinder, for which you need to buy a special attachment - a diamond wheel on concrete, otherwise you will hardly be able to cut the tiles.

The technology of laying paving slabs on a concrete base

Since we are not talking at all about how the screed is poured, which, presumably, we already have, let's talk about how to lay paving slabs on a concrete base, what is required to do this and how to properly distribute the work in stages. Everything is quite simple, because even a beginner can figure it out, so don't worry, but you will have to put a lot of physical labor, you should be ready for this.

Photos from the site: plitkasnab.ru

First of all, curbs should be installed, which will beautifully outline the boundaries of the paths, and also prevent the tiles from "creeping" into different directions... From the level of the base of the screed, you need to go deeper under the curb by another ten centimeters, pour a five-centimeter layer of sand on the bottom, then lay the same amount of cement-sand mortar, and only then install the curb element itself. It is required to align it along a stretched cord, but orientation, relative to the horizon, should be carried out using a level. After installation, all work must be stopped for a day so that the solution at the base of the curbs grabs.
A small layer of rubble is poured, about three to five centimeters, which will serve as a pillow, and at the same time drainage. This layer needs to be properly leveled with a rule, and it is also necessary to check it with a level, only after that you can do it thoroughly tamping.
On top of all this, an additional layer of sand mixed with cement is poured in a ratio of five to one.
It is on the sandy surface that the paving slabs are laid and compacted very carefully with a special rubber hammer. First, the main plane should be paved, and only then the pieces and edges should be cut, but it is worth considering that it is imperative to leave a gap between the tiles, at least 3 millimeters. This is done so that in the cold it does not burst and deform.
A rammer is installed on the surface of the laid tile and passes over the entire plane.

Sprinkle the entire surface on top with the same sand mixed with cement and a broom, very carefully place it over the entire plane so that the mixture evenly fills all the cracks. The rest of the sand is also swept away with a broom or broom. This is followed by the stage of spilling with water. This can be done with buckets, or you can use a garden hose, especially if there is an irrigation system.

It is necessary to ensure that the solution does not wash out of the cracks and gaps, but, on the contrary, reliably settles in them. You can repeat the last steps several times until the best result is achieved. Also, if you wish, you can seal the tile joints with grout, but this is not at all necessary. Laying paving slabs on concrete is not at all difficult, even a beginner in the construction business can do it, so do not worry, you just need to get up and do it, and all the subtleties and nuances can be seen in the video.

How to put paving slabs on a concrete base: all stages of installation

On the territory of a private house, large shops, car parking areas, you need a coating that can withstand increased loads. To solve the problem, you will need a concrete pillow. Let's figure out how to put paving slabs on a concrete base on our own, and ensure the reliability and durability of the cladding.

Can it be laid on concrete?

Walkway tiles are generally laid on a cushion of sand and gravel that is formed directly above the ground. But, such a base cannot withstand a large weight with loads. For the improvement of children's areas, car parks, footpaths, they use the technology of laying paving slabs on a concrete base. A concrete cushion is able to provide reliability and strength to the cladding.

One of the important arguments in the question of whether it is possible to lay paving slabs on concrete will be both the strength of the coating and its moisture resistance.

The method of laying paving slabs on a concrete base has the following advantages:

the ability to take increased loads;
resistance to unforeseen damage of various nature;
simple installation technology;
you can do it yourself when laying.

You can put paving slabs on concrete, and during further operation, the coating will not sag if you follow the installation technology requirements.

There are also some disadvantages when laying paving slabs on concrete:

installation is more laborious when compared with a sand cushion in combination with gravel;
if one element of the coating is damaged, then when it is removed, there is a possibility of damage to adjacent parts;
if the rules for installing paving slabs on a concrete base are not followed, the concrete pillow may crumble after the first winter season.

One of the main problems with concrete paving is moisture. When moisture gets into the cracks of the tiles, and with their further freezing in winter, the coating literally breaks from the inside. The deformed coating may come off the base. Therefore, before you start laying tiles on a concrete base, you need to take care of high-quality drainage and drainage design.

It is possible to lay paving slabs on concrete, but it is necessary to correctly install the coating.

Installation steps

Before starting work, read the video below on laying paving slabs on a concrete base, as well as step by step recommendations... It is important to follow the installation rules so that you do not have to do the work again.

Paving slabs on a concrete base are mounted in several stages:

preparatory activities are carried out, which include measurements and marking of the treated surface;
preparation of a concrete base;
installation of the border;
surface cladding.

If you put paving slabs on concrete, according to the steps listed, the coating will last a long time and will not require unscheduled repairs. Let's consider each stage of work in more detail.

Required tools and accessories for installation

To perform facing work, you must use the following devices and materials:

container for mixing the solution. It is good if there is a concrete mixer;
sand;
cement (grade M500);
crushed stone;
hydro levels (2 pieces). One device - 50 cm, the second - 100 cm;
device for compaction of the base (rammer). You can use automatic or manual option;
a stronger rope, pegs for marking the boundaries of the covering;
trowel (special trowel for applying mortar);
rubber hammer;
watering hose;
rake;
broom.

Tools with accessories are selected, and you can proceed to the next step.

We calculate the amount of facing material

In order to eliminate unnecessary costs, and after the installation is completed, there are no unused elements left, it is necessary to mark and calculate the required number of paving slabs for concrete. Correct measurements and calculations will give you a good surface finish.

Position Calculation principle

Sidewalk tiles	Measure the perimeter and surface area for the cladding. The number of tiles is calculated by the sum of all the areas of surfaces to be faced. To the resulting figure, you need to throw 10%, in cases of marriage or other unforeseen circumstances
Building components for bulk base	Calculated taking into account the thickness of the pillow layer. For the calculation, the area of \u200b\u200bthe entire working surface (in m2) is taken, and multiplied by the width of the future coverage (in meters).
Curb stone	The required number is the length of all perimeters, from which the length of the places where the surface adjoins the base is subtracted
Concrete cushion components	The calculation depends on the density of the pillow. So, if you need to make a pillow of B20 grade concrete (for 1 m³), \u200b\u200byou will need approximately the following amount of components: cement - 320 kg, gravel - 1150, sand - 770 kg. It will take about 180 liters of water

After the calculations, you can proceed to the main preparatory activities before laying paving slabs on the concrete blind area.

Preparatory activities

The quality and durability of the future coating depends on the competently performed preparation before gluing the paving slabs to concrete.

First, prepare the soil:

soil is removed from the marked working surface (to a depth of 25 cm), in such a way as to go beyond the marking by the thickness of the future border, and throw another 3 cm.Stones and plant rhizomes must be removed from the pit;
the bottom must be leveled with a rake, then water it with a hose and tamp the soil well.

Making a concrete pillow step by step

In order to put paving slabs on concrete with high quality, it is necessary to make the correct base. If the technology is violated, the surface will soon crack.

The pillow is made as follows:

the bottom of the prepared trench is filled with a special volumetric honeycomb structure (geogrid) to hold the cover on the bevels, then it is covered with a layer of gravel (15 cm). The edges of the grate should be lower in height than the filled up gravel, so as not to interfere with tamping;
the resulting layer is well rammed;
a reinforcing mesh is installed on top;
according to the contour marking, a temporary flooring (formwork) is installed, which will be filled with concrete during installation;
while concrete is being prepared, it is simultaneously poured into the flooring to eliminate voids. Voids can affect structural strength;
the finished base is covered with foil and left in this state for several days (from 3 to 7). From time to time it is necessary to wet the finished base with water.

To remove moisture that has entered or may seep to the concrete cushion, cuttings of polypropylene pipes are installed at regular intervals. The top of the pipes is placed in such a way that it coincides with the top of the pillow, and the bottom goes into the layer of gravel. After the concrete layer has completely solidified, the formwork can be removed.

Installation of borders

When the formwork is removed, curbs need to be installed in the resulting grooves. To carry out the work, a concrete solution is prepared, and with the help of a trowel it is laid in the ditches. From above, one by one, curb stones are mounted.

A rubber mallet is used to fix the curbs. The remaining gaps must be filled with a liquid concrete layer.

In order not to interfere with waste water, when installing curbs, observe their height. It should be below the top of the paving stone (30 mm difference). After a day, the solution will harden, and the resulting space between the curbs and the walls of the ditch must be covered with sand.

Surface cladding

After the above measures have been taken, you can proceed to the final stage - to lay the paving slabs on the concrete base. Before performing the installation, it will not be superfluous to familiarize yourself with the video below on how to lay paving slabs on concrete.

If the lined surface is supposed to be used as a walkway, then the thickness of the lining element can be from 4 to 5 cm.If a parking space for cars is being arranged, then select the lining elements with a thickness of 6 cm.

There are two ways to lay paving slabs on concrete:

apply a dry composition of sand with cement;
use a mortar of cement with sand.

Let's take a closer look at how to glue paving slabs to a concrete base using the above methods:

Important: if you lay paving slabs on concrete treated with a dry mixture, then without additional devices such a technique will not hold the facing material. Therefore, when you put the paving slabs on the concrete blind area, it is necessary to thoroughly soak the structure with water. Moisture will seep into the resulting gaps between the tiles and the dry mixture will harden.

To install paving slabs on a concrete base, you need to use a rubber hammer, which is used to hammer the facing into the cement-based mortar.

Close up the seams

Correctly laying paving slabs on concrete means observing all stages in the process of work. When the facing stage is completed, you need to take care of the grouting.

You will need a dry mixture of sand and cement, with the help of which the remaining seams and gaps are filled in. After processing, the seams are spilled with water. Repeat these actions until the mixture stops settling.

Leave the surface for three days to dry completely. Then you can start cleaning, and sweep up the resulting dust with a broom. At the end of cleaning, the finished lined surface is washed with a hose using a strong pressure.

If the concrete pad is old

Walkways or other surfaces are not always lined with fresh concrete. It is possible to lay paving slabs on an old concrete base. Retrofitting an existing pillow will take less time and money. But there are some nuances to consider. Laying paving slabs on old concrete is shown if the base is relatively intact and has no visible defects.

You can put paving slabs on old concrete as follows:

first you need to carefully inspect the used base;
clean the surface from crumbs, debris, sand. If there are oil stains, they can be removed without problems with a solvent. The main thing is that the work surface is cleaned;
existing surface chips, pits, cracks are filled with a cement-based solution. The surface must be leveled so that a slight slope is obtained;
further, you need to lay the paving slabs on the used concrete blind area in the same way as on a new base.

Important: if, when examining the old concrete pad, serious defects are found, then the facing cannot be performed. Otherwise, during operation, the surface will not withstand the load and deform. If the blind area of \u200b\u200bpaving slabs on a concrete base is strong and looks reliable, then using the pillow a second time can save a lot.

Compliance with safety measures

Facing paths or parking spaces is a construction work, so it is important to take precautions during the work.

In order to lay tiles on concrete outside, and not harm your health, you must adhere to the following precautions:

to protect the lungs when working with cement mortars and dry mixtures, you must use a respirator;
to protect your eyes, use special glasses with shatterproof glasses, which will come in handy when cutting the facing material;
concrete can adversely affect the skin, so protect your hands with gloves;
upon completion of work with concrete mortars, all tools used must be washed and cleaned immediately. Otherwise, after the concrete hardens, it will be difficult to wipe them off;
do not cut or split the tiles on your knees.

Do not forget that the tiled surface can be used no earlier than three days after the end of the work. For structural reliability, install temporary fences.

When performing work, it is necessary to strictly observe not only safety measures, but also the step-by-step process technology. With the correct execution of facing measures, the coating will not crack on frosty days, the tile will fit snugly to the concrete base. Parking lots and walkways will last a long time and will not require unexpected repairs if the instructions are followed.

Classic pavement tiling involves the creation of sand and crushed stone cushion. But if the future surface is exposed to large physical activity, then laying paving slabs on a concrete base will help to cope with them. Such coverage will be effective in areas that involve the organization of car parking or active pastime.

Paving concrete has many advantages. It provides a long service life of the lined areas, their resistance to deformation due to moisture and temperature extremes. In areas refined with this method of laying, practically no grass grows, which makes it easier to care for the coating.

It is also important that laying paving stones on a concrete base with your own hands will give you no less pleasure than contemplating the work of a specialist. If you want and have the baggage of the necessary knowledge, you can independently cope with this task. However, it should be remembered that, with apparent simplicity, laying paving stones on a concrete base requires strict adherence important rules, ignoring which can lead to the complete destruction of efforts. If you are unsure of your building talents, take advantage of the skills of the professionals.

Paving methods

Paving slabs are laid on concrete using:

mixed in appropriate proportions of sand and cement;
their solution;
special glue that gives a strong adhesion.

Dry styling

To lay the sidewalk in the first way, it is necessary to prepare a dry pavement, taking into account correct proportions... Well-mixed components are poured onto the concrete surface in a layer of 5-6 cm. Tiles are carefully placed on them, which is carefully fixed with a rubber hammer. After completion of work, the mixture is poured with water several times in order to ensure a tight adhesion of its components.

Laying with mortar

A liquid cement-sand mortar should be thicker than the one that is being prepared to form a concrete base. It is laid out in a layer up to 3 cm, into which the coating elements are pressed with hands and a rubber hammer.

Waterproof adhesive is often used when working on concrete with clinker and granite material. The process of such styling requires certain skills, since it does not involve correcting a large number of errors.

Whichever method of installation you use, during and after the end of the work process, you should ensure that the level of the laid surface is checked. Working with concrete or glue loves efficiency and accuracy, in the absence of which it is impossible to achieve a good result.

For those who are wondering how to properly lay paving slabs on concrete, information on existing laying schemes is important. As a result of the work carried out, we want not only to obtain a high-quality surface, but also its aesthetic appeal. The paving stones offered by the market to the modern consumer provide tremendous opportunities for creating interesting patterns. Clinker and granite tiles can make real paintings that will become a real decoration of the landscape.

The technological process of laying tiles of different types on a concrete pad

The technology of laying paving slabs on a concrete base is simple. However, in order to achieve the highest possible result, it is important to follow a number of rules:

firstly, before starting the working process on the site, high-quality drainage and drying should be carried out, since water flows that have entered the zone of the concreted surface will turn into ice crystals and deform the coating with decreasing temperatures;
secondly, the concrete pad must be laid at a slight angle in order to ensure the drainage of water falling on the path (platform, blind area);
thirdly, the concreting of the site cannot be carried out in rainy weather, this will interfere with the high-quality adhesion of the components of the mixture.

Initial stage of the workflow

The process of laying paving stones on a concrete base takes place in several stages. First you need to select and inspect the site, analyze its main characteristics regarding strength, slope angles and soil moisture. The next step is the selection and purchase of the necessary materials and tools at hand. It is important to correctly calculate the number of tiles, taking into account the unforeseen expenses that may be needed to correct errors. The last preparatory stage before the main work is the marking of the territory with the help of pegs and a stretched rope.

Preparing a concrete base

Paving begins with the preparation of the concrete base, which is the foundation for future success. If the concrete surface is not created correctly, you will not get quality masonry. The formation of a concrete cushion begins with the preparation of a liquid cement-sand mortar with the addition of crushed stone. It is important to remember when laying paving material with your own hands about the proportions of the components that make up the concrete. Their classic ratio of 1: 3: 2 allows you to get the desired consistency.

The foundation pit itself is created in this way:

remove soil to a depth of at least 25 cm;
clean the resulting surface from foreign objects and plants;
crushed stone is poured into the depression, the layer of which should be 10-15 cm;
they build a reliable formwork, the boards of which are at least 40 cm thick;
after tamping the crushed stone in the pit, 3-5 cm of the prepared sand-cement mixture is poured onto it, a mesh of strong reinforcement is laid on it;
at the end of the work, the layers created in the pit are again poured with concrete, the thickness of which is 5-10 cm, depending on the nature of the further use of the created surface.

In the process of forming a concrete pad, all of the above steps are important. But it should be emphasized once again that it is necessary to strictly observe the proven ratios of ingredients in the composition of concrete when you lay out paving slabs with your own hands. A fragile base can be subject to erosion by water, deformation under the influence of a large load, which contributes to the rapid withdrawal of the laid out area from normal operation.

We form curbs

For areas lined with paving slabs, curbs are needed that will help to firmly hold the created structure. For their formation, it is advantageous to use the already laid markings, which were lined up for the purpose of pouring a concrete cushion. A narrow trench is dug along the stretched thread, taking into account the width of the material selected for the manufacture of the curb. A sand-concrete mixture is poured into it 3-5 cm, which includes one part of sand and three parts of cement. At the end of the pouring, the curbs are mounted and compacted special tools or by improvised means. After the first day, the remaining spaces between the stones and the ground are filled up and carefully tamped.

After the concrete base hardens and the border grows firmly into the allotted place, they begin to lay the tile material.

We lay the tile material

How to glue paving slabs to a concrete base so that it will serve for a long time and look beautiful? This is done in one of the three ways outlined above: by dry mixing of cement and sand ingredients, a slurry of cement and sand, waterproof glue.

If you want to lay paving slabs on dry concrete, the first and third methods are suitable. Using the first option for carrying out work, the surface is covered with a grinder, provided it is created from one part of cement and six parts of sand. The dry flooring is tamped and leveled. The adhesive is directly applied to a thoroughly cleaned dry concrete surface. The slurry is also evenly distributed over the concreted area. Pressing the tile, carefully spread it into the mixture or glue in accordance with the selected pattern. The work is carried out using a manual rammer, a rubber hammer, vibrating plates, with which the masonry is compacted.

As a rule, in some places, individual tiles need to be cut to fit into the planned space. You can complete this task using the grinder. In the case of using a grinder, after installation, the site is repeatedly filled with water, which allows the adhesive components to harden. The joints between the tiles are covered with a sand-cement mixture, which is also moistened to obtain better shrinkage of the coating.

Preparing tiles for use

After 2 or 3 days of drying, the area is restored to its proper form, swept and washed. It is fully prepared for use after thorough cleaning.

Technological nuances of laying clinker and granite paving stones

The technology of laying clinker paving stones on a concrete base is practically the same as when working with other types of tile material. It is laid out using glue and dry mixtures. As is customary, the seams are rubbed with a hydrophobic compound.

Technological aspects of laying granite paving stones on a concrete base are also consonant with classical approaches. Usually, new material small thickness is attached to a concrete pad by applying special glue to it. Chipped and old paving stones are laid out on a sand-cement base.

Working with old concrete base and blind area

Often, the owners of household plots ask how to put paving slabs on a concrete base that has already been in use before. Often the tracks require only some restoration to help prolong their active life. In order to place paving slabs on an old concrete surface, you should:

examine it carefully;
remove collected debris, chips, residues of varnish, oil or paint from it;
putty and smooth out irregularities;
remove areas with severe damage.

After the preparatory work, it is required to put the paving slabs on the concrete path as described above using a dry or wet mixture of sand and cement.

Features of laying the blind area

Laying paving slabs on a concrete blind area is practically no different from the usual procedure. It is important to consider that the width of the paving should be at least 40 cm, and it is advisable to put bituminous material and geotextiles under it.

Can it be laid on concrete?

One of the important arguments in the question of whether it is possible to lay paving slabs on concrete will be both the strength of the coating and its moisture resistance.

The method of laying paving slabs on a concrete base has the following advantages:

the ability to take increased loads;
resistance to unforeseen damage of various nature;
simple installation technology;
you can do it yourself when laying.

You can put paving slabs on concrete, and during further operation, the coating will not sag if you follow the installation technology requirements.

There are also some disadvantages when laying paving slabs on concrete:

installation is more laborious when compared with a sand cushion in combination with gravel;
if one element of the coating is damaged, then when it is removed, there is a possibility of damage to adjacent parts;
if the rules for installing paving slabs on a concrete base are not followed, the concrete pillow may crumble after the first winter season.

It is possible to lay paving slabs on concrete, but it is necessary to correctly install the coating.

Installation steps

Before you get started, check out the video below on laying paving slabs on a concrete base, as well as step-by-step recommendations. It is important to follow the installation rules so that you do not have to do the work again.

Paving slabs on a concrete base are mounted in several stages:

preparatory activities are carried out, which include measurements and marking of the treated surface;
preparation of a concrete base;
installation of the border;
surface cladding.

If you put paving slabs on concrete, according to the steps listed, the coating will last a long time and will not require unscheduled repairs. Let's consider each stage of work in more detail.

Required tools and accessories for installation

To perform facing work, you must use the following devices and materials:

container for mixing the solution. It is good if there is a concrete mixer;
sand;
cement (grade M500);
crushed stone;
hydro levels (2 pieces). One device - 50 cm, the second - 100 cm;
device for compaction of the base (rammer). You can use automatic or manual option;
a stronger rope, pegs for marking the boundaries of the covering;
trowel (special trowel for applying mortar);
rubber hammer;
watering hose;
rake;
broom.

Tools with accessories are selected, and you can proceed to the next step.

We calculate the amount of facing material

Position	Calculation principle
Sidewalk tiles	Measure the perimeter and surface area for the cladding. The number of tiles is calculated by the sum of all the areas of surfaces to be faced. To the resulting figure, you need to throw 10%, in cases of marriage or other unforeseen circumstances
Building components for bulk base	Calculated taking into account the thickness of the pillow layer. For the calculation, the area of \u200b\u200bthe entire working surface (in m2) is taken, and multiplied by the width of the future coverage (in meters).
Curb stone	The required number is the length of all perimeters, from which the length of the places where the surface adjoins the base is subtracted
Concrete cushion components	The calculation depends on the density of the pillow. So, if you need to make a pillow of B20 grade concrete (for 1 m³), \u200b\u200byou will need approximately the following amount of components: cement - 320 kg, gravel - 1150, sand - 770 kg. It will take about 180 liters of water

After the calculations, you can proceed to the main preparatory activities before laying paving slabs on the concrete blind area.

Preparatory activities

The quality and durability of the future coating depends on the competently performed preparation before gluing the paving slabs to concrete.

First, prepare the soil:

soil is removed from the marked working surface (to a depth of 25 cm), in such a way as to go beyond the marking by the thickness of the future border, and throw another 3 cm.Stones and plant rhizomes must be removed from the pit;
the bottom must be leveled with a rake, then water it with a hose and tamp the soil well.

Making a concrete pillow step by step

In order to put paving slabs on concrete with high quality, it is necessary to make the correct base. If the technology is violated, the surface will soon crack.

The pillow is made as follows:

the bottom of the prepared trench is filled with a special volumetric honeycomb structure (geogrid) to hold the cover on the bevels, then it is covered with a layer of gravel (15 cm). The edges of the grate should be lower in height than the filled up gravel, so as not to interfere with tamping;
the resulting layer is well rammed;
a reinforcing mesh is installed on top;
according to the contour marking, a temporary flooring (formwork) is installed, which will be filled with concrete during installation;
while concrete is being prepared, it is simultaneously poured into the flooring to eliminate voids. Voids can affect structural strength;
the finished base is covered with foil and left in this state for several days (from 3 to 7). From time to time it is necessary to wet the finished base with water.

Installation of borders

A rubber mallet is used to fix the curbs. The remaining gaps must be filled with a liquid concrete layer.

Surface cladding

There are two ways to lay paving slabs on concrete:

apply a dry composition of sand with cement;
use a mortar of cement with sand.

Let's take a closer look at how to glue paving slabs to a concrete base using the above methods:

To install paving slabs on a concrete base, you need to use a rubber hammer, which is used to hammer the facing into the cement-based mortar.

Close up the seams

Correctly laying paving slabs on concrete means observing all stages in the process of work. When the facing stage is completed, you need to take care of the grouting.

If the concrete pad is old

You can put paving slabs on old concrete as follows:

first you need to carefully inspect the used base;
clean the surface from crumbs, debris, sand. If there are oil stains, they can be removed without problems with a solvent. The main thing is that the work surface is cleaned;
existing surface chips, pits, cracks are filled with a cement-based solution. The surface must be leveled so that a slight slope is obtained;

In order to lay tiles on concrete outside, and not harm your health, you must adhere to the following precautions:

to protect the lungs when working with cement mortars and dry mixtures, you must use a respirator;
to protect your eyes, use special glasses with shatterproof glasses, which will come in handy when cutting the facing material;
concrete can adversely affect the skin, so protect your hands with gloves;
upon completion of work with concrete mortars, all tools used must be washed and cleaned immediately. Otherwise, after the concrete hardens, it will be difficult to wipe them off;
do not cut or split the tiles on your knees.

Do not forget that the tiled surface can be used no earlier than three days after the end of the work. For structural reliability, install temporary fences.

Laying paving slabs on a concrete base is highly durable and durable. This method of laying is used in places where intense loads are observed. But this method is quite expensive, so it is used only if there are appropriate technical requirements.

Paving slabs are traditionally laid on a sand-crushed stone base, which is arranged directly on the ground. However, this option is not always optimal. For example, when paving parking lots, playgrounds, pedestrian areas, it is very important that the foundation is as strong as possible. In such cases must be laid on concrete, which provides a high level of coating durability.

It should be remembered that the concrete base under the paving slabs is waterproof.

The main advantage of a concrete base is its stability... This is its difference from the sand-crushed stone cushion, which, under the influence of atmospheric conditions, can sag and "pull" the paving stones. This does not happen with a concrete base. The coating laid on a concrete base will not sag even under rather high mechanical stress, for example, in car parks.

The main enemy of the coating is moisture... Water penetrates microcracks, and when it freezes, it expands and destroys the tile from the inside. Therefore, before laying the paving slabs on the concrete base, it is necessary to ensure good drainage and drainage.

In the case when the tile is laid on a sand-gravel base, water does not stay on the surface of the tile, but seeps through the joints of the paving and is absorbed into the sand and gravel. This does not happen when laid on a concrete base. Water, passing through the joints, accumulates between the tiles and concrete... This leads to the fact that in frosty weather the water freezes and tears the material from the base. Therefore, it is so important that the laying of paving slabs on a concrete base is carried out according to all the rules.

Concrete base technology

The work should begin with the planning of the site where the paving slabs need to be laid on concrete. The site must be measured, draw its plan and apply all dimensions to it... After that, it is necessary to calculate the required amount of material for laying (this includes tiles, sand, crushed stone, cement). Then, using twine and pegs, you should mark the site according to the developed plan.

Now you can start removing soil... It must be removed to a depth of 25-30 cm. The resulting trench is cleaned of plant roots, a layer of rubble 10-15 cm thick is poured onto the bottom, creating the necessary slope for water drainage.

Plank formwork is installed along the stretched twine... The formwork must be secured with pegs. They are placed on the outside of the formwork at a distance of 0.8-1 m from each other. The thickness of the boards must be at least 40 mm. Otherwise, they may not hold the concrete mass.

For pouring the base, a concrete mixture of crushed stone, sand and cement in a ratio of 3: 2: 1 is used... The strength of the concrete base is reinforced with a reinforcing mesh. Therefore, first a layer of concrete 3-5 cm thick is laid out on the crushed stone pillow, a reinforcing mesh is laid on it, and then poured with another, 5-10 cm layer of concrete.

The top layer of concrete bedding under the paving slabs should not contain coarse gravel

At the stage of filling, slopes are formed. Paving slabs, their laying on concrete does not require too much slope, one degree will be enough. If concreting is carried out on a large area, it is necessary to make expansion joints every 2-3 meters to prevent deformation of the paved surface during seasonal temperature changes.

After the concrete has set, the formwork is removed and the installation is started. But before laying the flooring on a concrete base, curbs must be installed... To do this, a groove is dug around the perimeter of the concrete pavement. A layer of cement mortar with a thickness of 3 cm is laid on its bottom.The ratio of sand and cement in the mortar should be 1: 3. The curbs are driven into the solution with a rubber hammer and left to solidify for a day. After the solution hardens, the gaps between the curbs and the walls of the trench are filled with sandwhich is spilled with water and compacted.

Laying methods

It can be laid on a concrete base in two ways: on a dry mixture of cement and sand and on a cement-sand mortar.

When you start laying tiles, you must first lay it out on a flat surface, observing the drawing. This will help you understand how to lay paving slabs on concrete so that each stone is in place. After that, you can start preparing the mixture or solution.

The mortar is prepared in the same proportion as for pouring the concrete base, but its consistency should be thicker. It is advisable to put only sifted sand in the mixture. The prepared mortar is laid with a trowel on the base with a layer of 2-3 cm. The paving slabs are pressed into the mortar. You can correct its position with a rubber mallet. Wherein it is necessary to constantly check the horizontalness of the paved surface using a building level.

A paving slab coating made on cement mortar is considered the most durable, but it is completely unrecoverable. If the concrete deforms for any reason, then the tiles cannot be used for secondary paving.

Many, of course, are interested in how to lay paving slabs with their own hands using a grinder (dry cement-sand mixture). In this case, a 5-6 cm thick layer is first laid on the concrete base. The tiles are neatly laid on it and tamped down with a mallet.

The result of the work must be checked at the building level

The joints between the tiles after laying are filled with a cement-sand mixture and spilled with water. This procedure must be repeated several times until all seams are completely filled with the mixture. The paved area can be used 2-3 days after the last procedure.

Basic laying patterns

The owners of summer cottages and country houses want to see their possessions comfortable and effective. Therefore, it is very important for them to know how to put paving slabs on concrete beautifully. It should be noted that rectangular tiles (paving stones) allow you to create many schemes and options for beautiful styling.

The most common laying patterns are:

"column";
Herringbone;
"brickwork".

These patterns are pretty simple and look great with multiple colors. Usually they are used for paving paths, playgrounds and parking lots.

Features of laying on old concrete

Often, the sites already have old paths that you want to modernize. Therefore, many people have a question, is it possible to put paving slabs on concrete, which is already many years old?

This method is allowed, but in the case when the coating does not have large defects and is still quite intact. Otherwise, the old concrete coating must be removed and replaced with a new one.

Technology for laying tiles on an old concrete base:

the coverage should be revised first. All chipped pieces, sand, debris, oil stains are removed from the surface;
pits and cracks must be putty with cement mortar, and the bumps must be combed;
after preparatory work, the tiles are laid on the old concrete base using the same method as on the new one.

As mentioned above, if there is serious damage on the old coating, then it must be removed... Otherwise, the entire laying of the tiles may be damaged in a couple of years. If the old concrete base is strong enough, then it is impractical to remove it. Indeed, with its help, you can significantly save on the arrangement of the territory.

It should be said that for laying paving slabs on an old concrete base, you can use special glue... Before glueing the paving slabs to concrete, the surface must be cleaned of dust, sand and small debris. The concrete surface should not have any kind of paintwork or any other that could peel off. The best adhesion is ensured by rough surfaces made of smooth or aerated concrete.

Tile adhesive for outdoor use is suitable for laying tiles on concrete

Laying paving slabs has some tricks:

when laying, accurate measurements are of great importance;
when you start laying tiles, you should consider renting an electric sealant. Such a machine will help to achieve a smoother surface;
do not start laying tiles if there is a chance of rain. The cement mortar will not adhere well if it is too wet;
the top level of the tiles is best placed below the level of the lawn. If this condition is met, you can mow the lawn edges without worrying about damaging the mower or paving slabs.

Regardless of the basis on which the tiles are paved, they can last for a very long time if they are made with high quality, and all technological requirements are observed during installation.

How to put paving slabs with your own hands on the concrete base of the blind area is shown in the video:
