Today, paving slabs and paving stones are the most popular options for creating sidewalks and paths, including in a summer cottage or in a private house. True, after the first winter, the owner can expect an unpleasant surprise in the form of swollen or scattered paving slabs. What went wrong? It seems that someone has violated the construction technology while laying paving stones. Here's what you need to remember and do in order to prevent the tiles from deteriorating anymore.
The main enemy of any paving stone and paving slabs is water. Basis of Life has a bad habit of penetrating every crevice. The crotches between the tiles on the track are no exception. In general, there is nothing to worry about if, after passing through the cracks, the water has much further to seep. Otherwise, it will remain right under the tiles. With the onset of the first frosts, this is fraught with the fact that the tile will either begin to crack or be swollen.
Therefore, before laying tiles, it is important to make sure that there is a layer of materials underneath that have good transmissive properties. It could be any sand, gravel, screening out, rubble, geotextile … It is strictly forbidden to put paving slabs or paving stones on materials such as monolithic concrete, roofing material, polyethylene, clay. However, sometimes the tiles still need to be laid on concrete. However, in this case, there are some "tricks" that must be followed.
So, if paving stones are laid on concrete, then in no case should it be monolithic. In other words, there must be some kind of perforation. It comes in two main types. The first method of perforation is to create through holes in the concrete pavement all the way to the ground. The second method of perforation is to pour concrete with maps, separate segments, between which there will be gaps, allowing the water to go away.
