We all see a picture of peeling tiles on the porch almost every day, walking along the city streets. There is a porch near every store, and almost every third is not made very well, as indicated by the rebounding tile. But it is enough to adhere to an elementary rule to avoid this problem.
A porch, similar to a plinth, suffers from precipitation much more often than other structures. One winter is enough for the tile to peel off by the beginning of the next. This happens due to the regularly changing state of aggregation of the liquid. After all, water in any case enters the space between the structure itself and the tile.
Under the influence of temperatures, the water is able to expand, which leads to a slight degradation of the tiles. As a result, the pocket becomes larger and more moisture enters it. As a result, the tiles on the street just fall off.
Often the masters say that the technology was not followed during the work. In the case of laying tiles on the street, it is necessary to use special grouts and adhesives with increased moisture resistance and strength. Plus, there should be no voids, and the surface must first be well primed.
But that's not all. There is also a very important point that is often ignored. Usually, formwork is installed, a frame made of reinforcement and everything is concreted, which is wrong. After the cladding is done, the moisture that rises to the top finds an obstacle in the form of slabs. They are vapor tight. The water cannot rise further and at low temperatures freezing occurs at the junction of the slab and the base. The result is predetermined.
To prevent this from happening, you need to take care of waterproofing. Unfortunately, most masters don't think about it. You just need to compact the soil and lay a foundation. After a couple of days after that, make the waterproofing. Shut-off waterproofing does not take long, but it can get rid of a serious problem.
