Laying paving stones is an excellent solution for improving the local area, garden landscape and arranging a recreation area. You can do paving with paving slabs yourself - the technology is quite simple and does not require the use of professional equipment. Knowing some of the nuances of working with a concrete base, you will be able to create a beautiful, durable and wear-resistant coating.
Paving slabs on concrete: pitfalls of laying paving stones
Many people prefer to use paving stones as a finishing material for country houses, summer cottages, sidewalks, paving areas, gazebos and patios. Paving slabs are optimally suited for these purposes due to their performance characteristics:
- resistance to temperature fluctuations and the possibility of using cladding in regions with harsh climates;
- frost resistance - high-quality tiles can withstand up to 300-400 freeze/thaw cycles;
- high strength of finishing material - up to 300 kg/sq.s.;
- environmental friendliness of concrete paving stones - when heated, the slabs do not emit toxic substances, unlike asphalt
- on properly laid paving stones, no puddles form after rain - water is absorbed into the soil through cracks and storm drains;
- aesthetics and decorativeness of the coating - today manufacturers offer a wide range of models of different colors, shapes and textures;
- ease of installation - laying paving slabs with your own hands is not difficult, the main thing is to choose high-quality material and adhere to the technology;
- The service life of paving stones is about 15 years.
The use of tiles of various shades, the play of textured surfaces, and laying in interesting patterns like mosaics will enliven the landscape of the garden and the surrounding area. In addition, working with paving stones will allow you to maximize the talent of the designer and the artistic taste of the performer.
Traditionally, paving stones are laid on a crushed stone-sand base placed directly on the ground. This option is considered simpler. In areas with high traffic or for parking, a reinforced base is required to provide reliable coverage. In these cases, it is advisable to lay the tiles on concrete.
The technology of laying paving stones on a concrete base has its own characteristics:
- The tiles are laid out on a flat, prepared base - this ensures the stability of the finished coating. Even under the influence of regular mechanical loads, the tiles will not sag, and the paths will not lose their original configuration.
- During installation, it is necessary to ensure water drainage and drainage so that water does not stagnate on the tile covering. If this requirement is neglected, then moisture accumulates in the seams between the tiles, and when freezing, ice particles gradually tear the finish away from the base and, as a result, individual fragments swell and split at the edges.
Important! When pouring concrete, special attention is paid to drainage. Experts recommend creating storm drains, point moisture collectors, or laying a coating with a slight slope.
Features of choosing paving stones
When planning to lay tiles with your own hands, you should have an idea of what types of paving stones there are and how to choose the right facing material.
Before purchasing, you need to decide on the basic parameters:
- slab material and purpose;
- method of manufacturing paving slabs;
- shape and size of paving stones;
- quality characteristics of the tiles.
Depending on the raw materials used in production, paving tiles can be: rubber, wood, stone, clay and concrete. The choice of material is largely determined by the area of use of paving stones:
Modern paving stones are produced using one of the methods: vibrocasting or vibrocompression. One method or another determines the strength characteristics of the coating.
Features of paving stones produced by vibration casting:
- main purpose - paving areas subject to light loads;
- insufficiently precise geometry of individual slabs;
- clarity of the printed image on the paving stones;
- a wide selection of different colors;
- Great for arranging garden and country paths.
Plates made by vibration pressing:
- used for paving sidewalks, parking lots and roads;
- has high strength;
- Available in simple forms;
- limited color selection.
Most manufacturers produce paving stones in the shape of hexagons and classic paving stones. Some companies produce so-called "herringbone", "wave" and "rocket". The most convenient and versatile option is rectangular tiles. With its help, you can create patterns that imitate brickwork, “ladders” and “chess”.
Important! To work with paving slabs of complex configuration, you will need to create or order a design project.
An important selection criterion is the size of the tile. The smaller the dimensions of the individual elements, the more efficiently the load is distributed. For laying straight paths, the size of the tiles does not matter much, but for paving arched terraces it is better to use small paving stones. Circular figures are laid out with specially designed paving stones.
When purchasing, you need to check the product quality certificate and find out the main characteristics of the tile:
- number of defrost/freeze cycles;
- paving stone thickness (4 cm for pedestrians, more than 6 cm for bicycle paths, 7-8 cm for vehicles, 10 cm for truck traffic).
Advice. You can evaluate the quality of tiles by their sound. To do this, gently tap the tile against the tile. A ringing sound means high-quality drying and strength of the material. Deaf, on the contrary, indicates that the technology was violated during production.

Methods for laying paving stones on a concrete base
Paving on concrete can be done in one of the following ways: on a dry cement-sand “cushion” or on a prepared liquid mortar.
Laying tiles with your own hands (step-by-step instructions are shown in the photo).
The first method involves constructing a paving stone made of dry materials about 6 cm thick. The paving stones are placed tightly on a “cushion”, and the seams between the slabs are filled with a cement-sand mixture and watered. The procedure is repeated several times.
The second option provides durable and strong paving. However, when laying tiles on concrete mortar, the coating cannot be restored after deformation.

Tools and materials
To pave the path you will need the following materials:
- paving stones - purchased with a small reserve;
- curbstone;
- crushed stone fraction 10-20;
- sand;
- cement;
- water;
- crosses for styling.
The tools you need to prepare are:
- bayonet shovel;
- cord;
- concrete mixer or drill with a mixer attachment;
- level;
- rubber hammer;
- Master OK;
- grinder for cutting slabs;
- level for horizontal control;
- the rule is long and short;
- country rake;
- hard brush.
Marking and preparation of the site
Preparatory activities include:
Preparation and pouring of concrete solution
When mixing the solution, it is important to maintain exact proportions. To create a base for paving stones, take 1 part cement and 3 parts sand. The mixture should be quite liquid in consistency, reminiscent of thick sour cream.
Procedure for pouring concrete:
Important! When concreting a large area or a long path, expansion joints with a width of at least 5 cm are left every three meters.
Procedure for laying tiles
If the concrete base is properly prepared, there will be no problems with laying paving stones. Installation of paving stones begins from the curb. Laying is carried out in the direction from top to bottom in the direction of water drainage.
Apply a solution about 3 cm thick to the concrete and begin laying out the material. Paving technology is in many ways similar to laying tiles on the floor with your own hands. To maintain the same distance between the paving stones, you can use 4-5 mm plastic corners. The position of the laid tiles must be leveled with a rubber hammer. Check horizontality with a level.
Fill the gaps between the paving stones with sifted sand, and sweep away the excess with a broom. Water the finished coating with water. If necessary, re-cover the seams with sand and moisten.

The nuances of laying paving stones on an old concrete base
If there are old concrete paths in the yard, then they can be radically modernized and paved with paving stones. However, this method is acceptable for coatings that do not have significant defects.
Tile laying algorithm:
- Assess the condition of the coating.
- Remove debris, sand particles, grease stains and broken concrete fragments from the path.
- Remove bumps, cracks, and fill the depressions with putty.
- Apply tile adhesive intended for outdoor work to the surface.
- Lay out the paving stones.

For areas with high pedestrian traffic, car parks, and for sidewalks with places for cars to pass, it is better to lay paving slabs on concrete. The technology is designed for high loads. Concrete has a high load-bearing capacity, that is, it does not lose its functional qualities in the long term. Laying paving slabs on a concrete base is the key to a stable, time-tested coating.
With the help of tiles, paths, streets and squares are lined on the street, in a personal plot, and the blind area around a house or building is covered. It provides a convenient and practical tile covering for the movement of people and cars, as well as a well-groomed appearance of the landscaped area.
Advantages of using concrete for paving
Despite the higher cost of a concrete base, the prospect of preserving the paving stones in proper form for many years determines the customer’s choice.
Before deciding whether to use it as a base for paving slabs, you need to understand what advantages the material provides compared to laying it on sand and crushed stone.
Characteristics of concrete:
- strength;
- density;
- plastic;
- waterproof;
- fire resistance.
Durability that increases over time
The material has the ability to resist loads without collapsing, which determines its high load-bearing capacity. This characteristic of concrete depends on many conditions: the activity of cement, the quality of the constituent elements - sand, crushed stone, gravel, water. Conditions also influence:
- kneading;
- transportation;
- styling;
- hardening;
- age of concrete.
Density
The basis of the indicator is the ratio of solid matter in the material and pores that are formed as a result of the penetration of air or water into the mixture. For example, a concrete density of 0.9 means that the mixture is 90% solid and 10% voids. The denser the mixture, the better. In this indicator, the crushed stone base is significantly inferior, since its density is lower.
Plastic
After it has been poured onto the set concrete, the laying of paving slabs on the mortar begins. A solution of cement-sand mixture in a ratio of 1:1 is laid on it.
To do this, take dry masonry, river or sifted sand, add the same volume of cement, mix and fill the seams between the coating using a broom.
Sweep the tiles until all the cement-sand mixture is swept from it into the seams. If this is not done, then after the first rain the cement will be absorbed into it, turning it from colored to gray. The seams are swept in dry weather. The flagstone is laid using a level in accordance with the drawing.
In a situation where the customer wants to update old paths by laying them with a new modern coating on old concrete, it may turn out that the base is in unusable condition. A logical question arises: is it possible to lay paving slabs on old concrete?
A properly installed trough and good concrete will create a high-quality base for paving over many years. If the concrete does not have serious damage, failures or defects, then laying concrete paving slabs can be carried out according to the rules described above.
Before paving, the old base is cleared of debris and dust, cracks, cracks and chips are sealed with cement. After drying, level the surface. In addition to the cement-sand mixture, tiles can be installed on an old concrete base using liquid tile adhesive.
Conclusion
If the old concrete base has significant damage, then it is better to remove it and create a new one, otherwise the new coating will fall off after a few seasons. This is relevant for places with high traffic of people, and even more so the roadway.
Laying paving slabs on a concrete base with your own hands is a great way to improve the area near your house and create a stable area for parking a car. This technology differs from the more usual one using a cement-sand cushion. Let's figure out whether it is even possible to lay tiles on a concrete base and how best to do it.

Types of tiles
It is also important to distinguish the material by production methods: vibration-cast or vibration-pressed. In addition, natural stone is used.
To understand the question of whether it is possible to lay paving slabs on concrete, you should consider the strengths and weaknesses of this method.
Advantages of the method
This process inherently resembles the principle of performing facing work using ordinary tiles. You will need a strong, stable base and a cement-sand mortar to fix the elements on the surface.
The technology has a number of advantages:
- Strength. A concrete platform can withstand enormous loads. It is less destroyed over time and does not “creep”.
- Durability. The masonry will last much longer than with the standard method of fixing the elements.
- Limited shrinkage. Over time, the sand cushion sags, which leads to the destruction of the path. This risk is minimized when mounted on a concrete base.
- Resistance to precipitation. The solution, unlike sand, is practically not washed out under the influence of water. In addition, it better withstands freezing cycles.
- Reliability. Hardened glue combined with concrete is much more reliable than sand on a bed of crushed stone.
Durability is the main advantage
The tiles are laid using mortar, so it will be almost impossible to redo the work in the future.
Preparing the base
First, a hole is made in the soil. Usually 20-25 cm is enough to place all layers of materials in the required quantity. After the top soil is removed, it is compacted. For this, special tools and devices are used. If water was used during compaction, wait until the soil dries before continuing.
Immediately after this, install the curbs, as they go deeper than the tiles. For stability, a layer of crushed stone about 5 cm thick is first poured. Then a curb is fixed on the sides of the sidewalk and the laying of crushed stone continues. The total layer of material should be about 15-20 cm, depending on what load is planned on the surface in the future. Approximately in the middle, lay a waterproofing film. This way you can prevent the foundation from being washed out and moisture from penetrating upward from the ground.
River sand is used to compact the substrate and fill voids. It is poured in a small layer, unlike the traditional approach. To achieve the best effect, a vibration installation is used.
Layout of the base for paving slabs
To strengthen the concrete, lay reinforcement. This is especially true for large areas and driveways. Individual rods are placed perpendicularly and tied together with wire. They also use a ready-made mesh attached to side rods of larger diameter. To make a solution, you will need high-quality raw materials: cement, sand, water, screenings and lime. The mass is poured onto the prepared base, vibrated, leveled and left to dry under the film. Before starting finishing work, make sure that there are no voids in the base.
Laying tiles
The technology consists of using cement-sand mortar or frost-resistant tile adhesive intended for external cladding.
Using a straight spatula, apply the prepared mixture onto the concrete. In one go, 1 m2 of treated area will be enough. Laying is carried out according to the chosen pattern and is moved “towards oneself” so that the tiles do not float under the weight of the master. Fix the whole pieces first, and then add the cut pieces along the edges. Use a block or mallet to level the tiles. Joints are kept to a minimum and subsequently filled with sand and cement.
Use a level to check that the installation is carried out correctly. The surface must provide a drainage slope of 2 degrees per 1 meter.
If installation is done correctly, you will get a durable and stable coating for paths and areas on your site.
Laying paving slabs on a house or dacha area can be a good option for replacing paving stones. Traditional paving technology allows you to lay such a coating yourself.
Criteria for choosing high-quality paving slabs
Correctly selected construction and finishing material is a guarantee of high-quality and durable paving. It is necessary to lay out garden paths or a recreation area in the local area with frost-resistant and abrasion-resistant paving slabs.
The service life directly depends on the abrasion resistance indicators.. The higher the parameters, the more significant loads the coating can withstand without repair or replacement. The level of resistance depends on the materials used. A high-quality slab can only be made using quartz or pure river sand, M500 cement and hard rocks such as granite, marble and basalt.
Durability is determined by GOST 13087-81. Porcelain stoneware and paving slabs based on natural stone have the greatest resistance to abrasion. The vibration-pressed version of the paving concrete slab is less stable. No less important are frost resistance indicators, which determine the number of freezing and thawing cycles.
For paving, slabs are used, which are produced in accordance with the vibrocompression technology or the vibratory casting method. In the first case, elements are formed that have lower aesthetics and not varied in size or shape. However, these tiles are the most affordable, have sufficient color intensity, and the average service life is twenty years. The second option is characterized by obtaining fragments with complex geometry and a unique pattern. Such the material has a higher level of strength and frost resistance, and also has the advantage of being waterproof. The disadvantages include the rather high cost.

Installation of concrete base
The paving process can be carried out using an existing concrete surface, but laying involves the construction of a reliable concrete base.
Preparing the area for pouring concrete
Regardless of the type of paving, it is impossible to ensure effective drainage or drainage without maintaining a surface slope, which should be a couple of centimeters per meter of pavement length. The low level of water permeability of artificial stone paving causes the accumulation of water and its freezing/thawing. Constant changes in volume cause gradual destruction of the installation.
Preparing for concrete pouring:
- at the first stage, marking is carried out with pegs and rope, as well as preparing the base. Marking pegs are installed at a distance of 30-40cm;
- removal of turf and removal of the top layer of soil to a depth of 10-15 cm and arrangement of a sand cushion;
- compacting a sand cushion and installing formwork or installing curb stones in a trench previously dug along the sides of the path.
If the option of pouring concrete without installing formwork is chosen, then the curb stone is laid on a sand-crushed stone bed 50 mm high. The curb is fixed with mortar. The fence must be covered with soil and only after that a sand cushion is poured under the concrete.
Preparing the solution
Paving slabs can only be laid on high quality concrete. As a rule, the foundation for paving is poured with concrete with a strength of B-15, but if the site has a high level of groundwater, then the strength of the concrete increases to B-22.5, which has a positive effect on the service life of the coating. Sand for concrete must be sifted. It is also necessary to purchase a sufficient amount of gravel or granite crushed stone.
Standard composition of a cubic meter of B-20 concrete solution for pouring the base for paving:
- cement 290-320kg;
- sown sand 630-770kg;
- gravel or crushed stones 1080-1150kg;
- clean water 160-180l;
- plasticizers in accordance with the manufacturer's recommendations.
It is recommended to mix all components until homogeneous in a concrete mixer, which will help to lay the concrete layer as evenly and efficiently as possible.
Concrete pad pouring technology
Before pouring the concrete solution, all preparation rules must be followed, including the installation of dividing lintels. Reinforcement mesh must be laid on the prepared surface. with cells 10x10cm or 20x20cm, which will significantly increase the strength of the structure being built, and polypropylene drainage pipes are installed vertically. The solution must be poured quickly enough, after which the surface is leveled.
We determine the readiness of the concrete pavement for further installation
Outdoor concrete pouring of the base will harden faster and better if you cover the structure with polyethylene and also moisten the surface of the base for a week. If filling is carried out over large areas, then expansion joint gaps must be left every three meters. For this purpose, boards should be installed, which are removed after the concrete mortar has set. About a day after the concrete pouring, the formwork is removed and the drainage holes are filled with fine crushed stone.

Stages of laying paving slabs on a concrete base
There are several options for arranging paving using paving slabs, but the most high-quality and durable method is considered to be the method of laying elements of such a covering on a pre-prepared concrete base.
The undeniable advantages of this method are increased strength and excellent resistance to external factors of the entire paved surface.
Preparatory work
Before you begin the paving process, you need to check the base again for cracks and breaks, differences in height and voids. The horizontalness of the surface is controlled using a building level. If there are no complaints about the concrete base, then you can proceed to the next stage of preparation, which consists of cleaning the surface from cement dust and contaminants.
Installation of curbs and backfilling of cement-sand base
After dismantling the wooden formwork, the recess can be used to install curbstones. For this purpose, it is necessary to prepare rigid concrete, which is placed inside the recess using a trowel, and curb elements are installed on top. To give the border high strength, you can glue the elements to each other. For this purpose, glue is applied to the end parts of the fragments.
Paving slabs are laid on the so-called paving slab, represented by a dry cement-sand mixture. The leveled mixture must be moistened sufficiently well, which will allow all paving elements to be securely held on the surface of the concrete base. A cement-sand mixture is prepared from one part cement and six parts sifted sand without adding water. Gartsovka is poured onto the surface of the site in a layer of 50-60mm, after which it is leveled using a rule or a regular board. The fastening layer is compacted with a vibrating plate or with a conventional manual tamper.
Laying paving slabs
Paving slab elements can be laid in different ways. If paving is done using cement mortar, then a 2-3cm thick cement mortar is applied to the concrete base using a trowel and the tile elements are installed. A tight fit can be made with a rubber mallet. To create gaps of 3-5mm, special plastic crosses are used.
It is imperative to control the slope. After the solution has set, after about two to three days, the gaps between all the fragments are filled with sifted clean sand and then rubbed with a standard solution.
We hammer the seams
Experts recommend filling the seams with a dry cement-sand mixture, which is then spilled with water. This process must be repeated until the mixture used in the joints stops shrinking. At the final stage, you need to remove all construction debris from the surface, and also, if necessary, the bridge is washed with water from a hose under high pressure.
We use paving slabs for paving garden paths
Garden paths have not only a purely functional significance in the garden area, but are also a fully-fledged element of the local landscape. Paved paths help to visually divide a summer cottage into separate zones, so their shape should organically complement the overall design concept. The most common option in suburban households is paving with paving slabs, which has a number of advantages:
- no formation of surface puddles;
- preservation of all mechanical properties;
- no emission of harmful volatile fumes;
- good frost resistance;
- long service life of a quarter of a century;
- maintainability.
Paving slabs can have different shapes and differ in color. The color intensity is not lost during operation. Garden paths bear a small load, so paving can be done not on a concrete base, but on a loose surface.
Arranging a concrete base will require some skill, and even minor violations of paving technology shorten the period of operation and cause inevitable destruction of the masonry.
Professional paving specialists It is recommended to pay special attention to the condition of the drain during operation, since disruption of its functioning during several freeze-thaw cycles can become the main cause of destructive changes. In general, caring for the coating is not difficult and does not have any specific features.
Laying tiles on a concrete base with your own hands (video)
Paving slabs are a modern and high-quality material for arranging coverings in home and country areas. Such tiles are not only easy to install, but also completely undemanding to maintain, which explains the high popularity of the material.
Arrangement of garden paths is carried out in various ways, but not all of them can provide the best quality. A very reliable foundation is obtained if paving slabs are laid on concrete, because the material based on sand, cement and gravel has high strength characteristics. This option is especially relevant where there is significant pressure on the surface.
Main advantages of the method
Not everyone knows how to lay paving slabs on concrete, but many have an idea of the advantages of such technology. However, during the work it is necessary to take into account some nuances regarding moisture removal ().
In the case of a sand cushion, water flows freely into the ground without causing harm to the coating.
- High resistance to deformation makes it possible to use the material for a long period of time.
- The relatively low price of the final structure allows it to be used by a wide range of developers.
- The simple installation technology allows you to carry out the work directly with your own hands.
Note! When installing on a concrete surface, you should create point moisture receivers, linings and other water drainage systems, then the base will serve for decades.
Carrying out work
When performing basic operations, accurate measurements are of no small importance, because if the calculations are incorrect, operation can be difficult. The upper level of the covering should be below the lawn, then there will be no problems when mowing the grass at the edge. In addition, it will be possible to avoid damage to the cutting elements.
Creating a Foundation
A prepared platform based on a concrete mixture can increase the durability of the coating if all work is carried out correctly. If serious mistakes are made during pouring, cracks may occur, which will compromise the integrity of the top layer.
Before laying paving slabs on concrete, you need to arrange the base itself.
- The territory is immediately marked, after which a small pit is made. To do this, the soil is removed to a depth of 20-25 cm. This distance corresponds to the bayonet of a shovel.
- The bottom of the trench is carefully leveled and covered with a layer of sand from 10 to 15 cm. A waterproofing material is laid on the surface of the soil, which will prevent the slab from coming into direct contact with moisture.
- Formwork is made from boards or pieces of plywood along the entire perimeter of the site. The main elements, as a rule, are supported by pegs sunk into the ground at intervals of 80-100 cm.
- Using metal rods, a reinforcing mesh is made, which is necessary to improve the strength properties of the structure. It should be located in the central part.
- The basic composition is prepared: 1 part of M400 cement, 2 parts of sand, 4 parts of gravel and water. Mixing everything M300, which is widely used in the construction environment.
- The finished mixture is poured directly into the formwork to the desired level. It is advisable to carry out the process within 24 hours, otherwise you will have to make special notches.
Attention! If there is already a ready-made base in which it is necessary to create drainage channels, diamond drilling of holes in the concrete is performed. After this, you can begin subsequent work.
Covering installation
Before laying paving slabs on concrete, you should prepare a sand-cement composition with which the elements will be fixed. Typically, there are four parts of sand per portion of binder.
The amount of water determines the consistency of the solution.
- First, curb stones are installed on the outer sides. To maintain evenness, the laces are tightened. A sand-cement mixture is applied under each element.
- After this, the tiles are laid out on a dry base in compliance with the basic pattern. If the outer fragments extend beyond the curb, then the reinforced concrete is cut with diamond wheels.
- Having prepared a certain part of the coating, you can begin fixing the elements with a binder. To do this, throw the mixture onto the concrete surface with a trowel, after which each segment is leveled with a rubber hammer.
- At the last stage, the seams are sealed. The finished composition is drawn into a special gun and carefully applied between the fragments. After the solution has dried, the surface is treated with a brush.
Note! The alignment of elements during installation work is carried out using a building level, and the horizontal is checked after installation of each row.
Product selection
Depending on the production technology, vibration-pressed and vibration-cast tiles are distinguished. In the first case, the coating elements are able to withstand the most intense loads, and therefore are actively used in the construction of full-fledged automobile platforms. Vibrocast products are used for garden paths, recreation areas and other areas with low load.
When purchasing products, you need to pay attention to the surface. A shiny layer on top may be a sign of increased water content, and this has a bad effect on the quality characteristics of the material.
Final part
This instruction not only gives a clear idea of whether paving slabs can be laid on concrete, but also provides an opportunity to become familiar with the procedure for carrying out the work. The main difference from laying on a sandy surface is the use of a binder mortar ().
