One of the features of ceramic tiles is its basis, which is porous or dense. The greater the porosity of the base of the tile, the greater the water absorption — this quality of the tile largely determines its technical and operational properties. For example, a slight water absorption gives higher frost resistance of the tile, as a result of which the service life of ceramic internal and external surfaces increases. The service life of the flooring will be greater if it is made of tiles with a small water absorption. Tiles with a high porous base is most at risk of rapid damage and breaking
