When it is necessary to lay paving slabs on a concrete surface on the street

Paving stones can be arranged to create paths, parking lots, recreation areas, or car parks for both practical and aesthetic reasons. The conventional method of paving entails placing goods on sand or a dry mixture made of 1/5 cement and sand.

But artisans prefer a more dependable solution because such technology is unsuitable for locations with unstable soil. Paving slabs are being laid on concrete as one of them.

1. Soils that are subject to shrinkage. These include compositions with a small design resistance (silty sand, peat and embankment).
2. Heaving soil – can lead to the destruction of the coating due to uneven swelling.

Additionally, the craftsmen must independently design elements like blind areas, garden paths, screeds, garage or shed flooring, and others. Because of its durability, it is not practical to disassemble the concrete base.

The following details need to be considered when installing polymer-sand tiles:

1. Degree of soil heaving. If the blind area or concrete path has been in use for several years and has not been damaged, you can confidently carry out paving. However, when pouring a new screed, there is a chance that clay impurities will remain in the freezing layer.
2. Moisture. The screed and curbs on the sides look like a rigid body, and rainwater can partially penetrate into the structure. To avoid heaving, you should arrange an effective drainage system along the outer perimeter and insulate the blind area with extruded polystyrene foam.

Advantages and disadvantages of the method

The utilization of a concrete base for paving stone installation is highly sought after due to its robustness and ability to withstand substantial weights. Such a coating can support heavy loads and is impervious to the damaging effects of precipitation—something that a crushed stone-sand layer or soil typically cannot withstand. Additionally, it offers a surface that is even and has distinct forms.

1. Increased strength properties. Concrete is very strong and does not deform under load. The service life exceeds 30 years, so the preparation of the base for laying concrete is suitable for arranging parking lots, car parks and areas where people constantly walk.
2. Resistance to precipitation. If the installation rules are followed, the degree of frost resistance will be about 200 cycles.
3. Absence of shrinkage effect. During operation, sand and soil subside, which contributes to complete or separate deformation of the coating.
4. Reliability. After hardening, the adhesive base provides maximum fixation of the tile, so it does not move or fall out.
5. Affordable cost. You can buy paving stones at a low price, because.. modern and affordable materials are used for its production.

But only if the installation technology is followed can the aforementioned benefits be realized.

1. Difficulty in dismantling in case of damage. Since glue is used as a binding additive, if 1 element is deformed, it will not be easy to remove and repair it.
2. If the paving technology is not followed, the coating will be damaged after the first severe frosts.
3. Poor drainage of water and moisture. Together with curbs, the concrete coating creates a closed box in which moisture and water begin to accumulate. To prevent such problems, a comprehensive drainage system is installed around the perimeter. It needs to be insulated at a depth of 30-40 cm with extruded polystyrene foam. Also, seams and voids can be sealed with glue.
4. Masonry work can require large financial investments when installing decorative curbs.

Consumables and tools

In order to get the tile base ready, the following tools and supplies will be required:

1. Concrete mixer.
2. Sand mixture.
3. Cement not lower than M500 grade.
4. Crushed stone.
5. Construction levels of different lengths.
6. Device for manual or automatic compaction.
7. Pegs and marking cord.
8. Master OK.
9. Rubber mallet.
10. Watering hose or watering can.
11. Broom.
12. Rake.

Quantity calculation

You must mark and approximate the perimeter of platforms and sidewalks in order to accurately determine how much material will be needed for the next project. Additional computations ought to be performed in light of the information gathered:

1. Number of tiles. It is measured by the total area of ​​the future surface with the addition of 8-10% of the reserve. The additional number will not greatly increase the cost of work, but will save you from the problem of lack of material during the paving process.
2. Base components. They are calculated taking into account the thickness of the layer by multiplying the area in square meters by the thickness of the required layer in meters. The final value will indicate the optimal number of cubic meters of building material.
3. Curbstone. The amount of this material is measured according to the following principle: the length of the perimeters minus the length of the places of adjoining to the foundation of the house and other objects on the site.

Preparatory work

There are multiple steps involved in the technology used to lay tiles on a concrete foundation. In order to determine the future coating’s dependability and durability, preparatory work must first be completed. If all preparation guidelines are followed, the structure will be sturdy and able to support large loads.

1. The site must be marked with pegs and a nylon cord, and then remove the soil at a depth of 25 cm. The bottom of the trench is cleared of plant roots and stones. If there is loose soil, the excavation is made in such a way as to remove the entire fertile layer, since it is poorly compacted.
2. A rake is used to level the bottom. Then the surface is poured with water from a hose or watering can and is subject to additional ramming to prevent soil subsidence in the future. After such activities, the construction of the load-bearing layer begins.

You can make a lasting and beautiful surface for your outdoor area by installing paving slabs on a concrete base yourself. You’ll be guided through the entire process by this step-by-step guide, from preparing the concrete base to installing and fastening the slabs. Whether you’re improving a patio, walkway, or driveway, following our simple instructions will make it easy to achieve a polished finish. Prepare to take on this fulfilling do-it-yourself project so you can enjoy the fruits for years to come.

Step-by-step instruction

To determine whether paving slabs can be laid on concrete and how to lay various kinds of this material, you should carefully follow the step-by-step instructions and examine each stage of the upcoming project. It is preferable to use a three-dimensional geogrid, which is composed of synthetic materials shielded from putrefactive processes and harsh environments, to improve the quality of concrete pad manufacturing.

Any bulk material in the cells is reinforced by the structure, which forms a stable frame in the event of tension. It has been in use for more than 50 years.

Preparing a concrete pad

The following guidelines must be followed when setting up the tile base:

1. A geogrid is fixed at the bottom of the recess, and a crushed stone layer 15 cm thick is poured out. The edges of the structure should be below the level of the crushed stone and not interfere with free ramming.
2. The crushed stone-based cushion is additionally compacted, and a reinforcing mesh is fixed on top.
3. Formwork is placed along the contour of the marking and concrete is poured.
4. Next, the concrete mixture is mixed and carefully poured. At this stage, it is necessary to eliminate the appearance of voids and cold seams, which reduce the strength properties of the formwork. Vibrating equipment is used to compact the screed. To prevent rapid loss of moisture from the pillow, it is better to cover it with film. Over the next 3-7 days, the surface is periodically moistened.
5. After 2-3 m of coating, expansion joints are left, which are made from boards installed perpendicular to the formwork. In case of temperature fluctuations, they will prevent the pillow from breaking.
6. To remove moisture that may get to the surface, you will need to secure pipe cuttings made of asbestos cement or polypropylene. Their upper level should correspond to the level of the concrete pad, and the lower end is fixed on the crushed stone layer.
7. After the concrete has hardened, the formwork should be removed.

Installing curbs

It’s important to install curbs when determining how to lay paving slabs on concrete mortar. After removing the formwork, they are positioned and filled with rigid concrete in the remaining recess. The structures must be driven into the mortar using a rubber mallet. Liquid concrete needs to be poured into any gaps and fractures.

In order to provide efficient drainage, the curb height is set 20–30 mm below the top of the paving stones. A mixture of sand is placed between the walls and the stones after a day.

How to properly lay tiles on a concrete screed with your own hands

It should not be too difficult for a novice to learn how to lay tiles on glue and concrete if they follow the detailed instructions. The sizes of the slabs are chosen with consideration for their intended uses: structures with a thickness of 4-5 cm are adequate for the configuration of sidewalks, and larger paving stones are preferable for parking lot organization.

A thin layer of cement-sand mixture, three to five centimeters in thickness, needs to be poured on top of the concrete if you plan to use dry cement-sand mortar to lay tiles on top of a concrete base. The surface is leveled with a board or a rule with even edges. The slabs are then put on top of the cushion.

Take one part cement and six parts sand to make a dry cement-sand mixture. The site is heavily watered, which fills the pores and encourages the mixture to harden, making it robust and resistant to destruction.

Installation on cement mortar

Cement mortar is the easiest material to work with when installing tiles on concrete. The technology has a longer service life and is simple to use. The following advice and suggestions should be taken into consideration to guarantee premium paving:

1. The optimal thickness of the cement layer is 2-3 cm. In this case, the cladding will be held in one place.
2. To speed up the filling process, the solution should be applied within reach of hands and leveled using a notched trowel.
3. After this, porcelain tiles, tiles or paving stones for garden paths are laid.

A building level and rule are used to monitor slopes and surface evenness. The area must first be filled with solid tiles, and any extra glue in the cladding areas needs to be scraped up using a trowel or spatula. The scraps must be cut out and put at the installation site once the mixture hardens. Seam areas are completely moistened and covered with sand or sandpaper.

For tile adhesive

The type of coating and several other factors should be considered when selecting adhesive for paving slabs on a concrete base (many adhesive base options are available in Moscow stores).

1. The adhesive base has a relatively short service life, and adjusting the placement of tiles after fixing will be problematic.
2. The composition is mixed in a small volume, taking into account the qualifications of the specialist.
3. The diluted glue is applied to a smaller surface in a layer of 0.5-1 cm.

Just like in the last instance, the seams need to be sealed with glue or a hartsovka.

Laying on a dry mixture

A dry mixture may be used in rubber tile installation technology. The following guidelines need to be followed in this situation by the master:

1. The hartsovka is created on the basis of sifted sand and Portland cement.
2. The composition is placed in a trench in a layer of 5 cm.
3. The surface is additionally compacted with a vibrating plate, and the tiles are hammered with a rubber mallet.
4. Places with complex geometry are cut out, and the entire surface is tamped again.
5. Hartsovka is used to fill the seams.

When paving, you can already move freely across the surface thanks to this technology. In addition, it offers good product repairability in the event that heavy loads cause splitting or deformation.

Sealing joints

A dry cement mixture is poured into the seam areas and then wet down with liquid. Until the cement-sand mortar eventually stops shrinking, the process must be repeated. You must remove construction waste and dust and small debris after two to three days. Additionally, you must use a hose to rinse the surface with water.

How to avoid mistakes

You must understand the tile-laying guidelines and learn how to lay tiles by hand if you want to avoid problems later on.

It is imperative to choose path and platform parameters promptly, adhering to the principle that complete tiles can be placed in between edges. This will prevent waste and unnecessary expenses.

The paving stones are ground using a grinder equipped with a stone surface processing disc. The tile is chipped off after it is cut to lessen the amount of dust. It must first be applied to the chosen location, marked, and cutted.

In order to ensure efficient drainage of surplus water and moisture, facing surfaces are positioned with a small slope. A surface height differential of 5 mm per m is ideal.

The paths must be slanted to one side to accommodate the quirks of installing tiles on old concrete or a sand base. To ensure that all rainwater or other liquid is directed in one direction, the central components should be positioned marginally higher than the other elements. If not, the paving stones will be destroyed by freezing and standing moisture.

A specific type of glue must be used to prepare the base for paving slabs produced using the vibration casting method. Better fixation is provided with the least amount of thickness.

Nearer the pouring location, the solution is mixed. However, it is preferable to decline mixing if the outside temperature is below zero.

Step	Description
1. Preparation	Clear the area of debris and vegetation, then level the ground.
2. Base Layer	Lay a layer of gravel or crushed stone, and compact it firmly.
3. Concrete Pouring	Mix and pour concrete over the base layer, and smooth it out.
4. Setting Time	Allow the concrete to set and cure for at least 24 hours.
5. Laying Slabs	Start placing the paving slabs on the concrete base, maintaining even spacing.
6. Filling Gaps	Fill the gaps between slabs with sand or a suitable filler material.
7. Final Touches	Compact the slabs gently and sweep the surface to clean up.

Enhancing your outdoor spaces with paving slabs laid on a concrete base is a sensible and long-lasting option. You can achieve a long-lasting, professional-looking result by carefully following the instructions. In order to guarantee the stability and durability of your paving slabs, it is imperative that you take the necessary time to prepare the concrete base.

Making sure the concrete base is level and fault-free is one of the most important steps. The slab laying process itself will go much more smoothly thanks to this foundation work. Prior to beginning the slab placement process, carefully plan the layout. This will help you avoid making any awkward cuts or adjustments later on.

Your best friends when placing the slabs will be accuracy and patience. Before moving on to the next slab, make sure the previous one is securely in place. Use spacers to keep the gaps between the slabs uniform. This meticulous process will make your paving seem tidy and consistent.

Don’t forget to add the final touches. In addition to improving the appearance of your paving, filling the joints with sand or grout keeps weeds out of the spaces between the slabs and helps keep them firmly in place. Maintaining your paved area on a regular basis, with occasional re-sanding and sweeping, will keep it looking fantastic for many years.

Installing paver slabs on a concrete base can be a rewarding do-it-yourself project if you have the right tools and put in a little work. If you do these things, you’ll have an attractive and useful outdoor area that you’ll be happy to show off. Cheers to your pavement!
