Reliable laying paving slabs on a concrete foundation

Laying of paving slabs on a concrete base ensures the reliability of the track area as a whole.

That's right, because the concrete eliminates "walking" tiles, is able to withstand heavy loads.

But sometimes, when stacking technology is broken, it may cause a backlash.

Most often, concrete foundation is used in cases, if you plan a great burden on the paved surface, it can be parking, storage of heavy equipment and so forth.

main task to be solved when laying paving tiles on concrete, is the organization of drains.

if they remain unnoticed, then after a time, you can watch the destruction of the masonry.Why is this happening?

Water falling on the tile, seeping through the seams and is under the cover of a long period of time.

In the case of changes in weather conditions: freezing, warming, water freezes and begins to literally push the laid tiles.

Therefore laying paving stones on a concrete base, with first priority should be to think not so much about what kind of load will be given to it, and how to organize the removal of excess moisture.

for this are livnevki, point vlagopriemniki, do tilt and so forth. The process of the work difficult, but with their own hands to make laying tiles possible.

Preparation of the base under the paving stones

concrete substrate is a monolithic flat area, the processlaying tiles which takes place in a simpler way than on a cement-sandy base, due to the solid support.

next working technology.It all starts with marking the area in which planned to build a track.To do this, set along the perimeter stakes, among them pull a cord.

It will serve as a reference.The height of the yarn should be at the level tile finishes in what.

to leave a distance between the cord and the ground not less than 30 centimeters.Otherwise, the soil layer is removed.

Also, it is done to the surface on which the base will be located, it has been flat.Stones, roots - all irregularities are removed.

done with a slight tilt to the side opposite from the building, or any other buildings, near which the track (area) is formed.

curbs installed The edges of the cleaned surface.Can they replace the temporary wooden formwork.

The first option is preferable for those who are going to make all the work with his own hands, not having much experience.Thus the fixed tiles during installation, are excluded shifts curvature.

Border must keep pace with the paving tiles, so the cord stretched above will serve as a guide here.

If the height of the curb is, for example, 50 centimeters, and opened after removing the surface soil to a height of 30 cm, at the edges of the recess must be level 20 cm below the ground.

also be taken into account for approximately 3 centimeters on a cement-sand mortar (in a ratio of 1: 3), by which the fixed borders.

Fit can be using the mallet - rubber mallet.After one day the solution solidifies, the gap left by the previously with both sides on the walls of one centimeter between the curb and the recess is filled with sand, wetted with a small amount of water and compacted.

After this work, you can start the installation on concrete foundation.One way to remove excess moisture, is the location of asbestos pipes over the entire surface.

technology is that the tube is cut into pieces, the size of which is determined the height of the concrete layer, the latter surface will be poured.

Next set one part of the tube for 1 sq.m vertically.After pouring the concrete, they are not removed.

can replace pipe wooden planks stacked in such a way as to obtain a square, clean up after the work done that is necessary.

Then poured a layer of crushed stone or gravel thickness should be 15 cm, compacted.

If you plan to use the site for heavy machinery, it is necessary to put the rubble reinforcing mesh.Kneading and concrete is poured in layers.

gap between this work should be one or two days, the first layer has hardened a bit.

If a large area of ​​filled surface, then every 3 m expansion joints are made: on the edge of the board is set up to 1 cm thick

After setting concrete planks are removed, the resulting joints are filled with elastic material..Such action prevents faults that may occur due to the temperature drop.

last layer of concrete becomes more fluid, because it is a leveling.
possible method of laying tiles on the old concrete base.

do it better when the planned paving of the pedestrian walkway, then there is a large load on the paving stones are excluded.Otherwise, it may cause deformation of the brickwork.

Laying of paving slabs

Laying of paving slabs on the concrete in two ways: on the sand-cement mortar and sand and cement dry blend.

Before you get started, you need to make a preliminary laying paving slabs on the concrete in order to identify patterns, drawing, leave a mark if necessary.

1. The first method involves a thick consistency solution than when pouring the concrete base.To prevent ingress of small stones, sand sifted better.These actions are necessary to correct a paving stone blocks with his hands.The layer of the solution (2-3 cm) is applied with a trowel and level the building;
2. second method involves the use of sand and cement in a ratio of 3: 1.His hands made the dry mixture and spread out on the prepared base.Then all it leveled and compacted.Laying pavers is done by mallets.When the track (area) to be laid, then it abundantly watered.We give some time to the fact that the tiles has dried up, and start grouting.Then the track again abundantly watered, washed away all the dirt and the remains of cement and sand.

process of laying paving slabs can be seen on the video.

General recommendations when laying tiles

Laying of paving slabs on the concrete starts from the curb.The move should be in the direction in which will have to drain the water.

is not advisable to put paving joint to joint, it is necessary to leave gaps of about 5 mm.This is called the expansion joint, which allows you to exclude fracture, possible motion curving tiles.

It will be easier to achieve smooth masonry, if you use the two levels.The first, shorter, is required to verify the correctness of stacking standing next tile.

second, longer, to verify much of the styling.

stack a tile slight indentation in the solution.Align paving rubber hammer or mallet.

If the tile is placed unevenly, it is possible to use a wide board, which is pressed a number of paving stones.Board rattles rubber mallet.

This alignment method allows you to avoid the use of compactors.The difference is that the vibratory plates are on the completion of work, the board - laid after each number.

seams between the tiles overwritten fine sand or sand-cement mixture.Sand contributes to the preservation of masonry, as well as the infiltration of water, so the drainage in this case must be made mandatory.

Grout sand-cement mixture creates a monolithic surface.Water penetration in this case is practically excluded.

But this method of grouting under high loads, such as race car on a platform, contributes to the appearance of cracks.

Any paving slabs, paving stones with changes in temperature tends to increase.Monolithic surface has expansion joints.

grouting process with their own hands is on the surface scatter the fine sand or a mixture of sand and cement, carefully begin to "sweep" the seams.The tool for this is an ordinary broom.

rules laying pavers

There are rules laying paving slabs on the concrete, which can not be ignored:

• impossible to conduct the work on paving the track in the rain;
• substrate must be flat;
• Laying tiles is carried out on a "top-down" or "myself";
• Always thought out drainage system (slope livnevki, drainage);
• first laid out the whole tile, cut - at the end;
• Sand with grout should be clean, with no plant roots and other debris;
• At the end of the work necessary to give the track (area) "rest" of 3-5 days;
• Pegs cord tension placed as often as possible, eliminating slack strands.
