Glassholst is the basis of flexible tiles, it is saturated with bitumen, which is called modified. He copes with moisture perfectly and prevents decay of materials. The tile is covered with a stone granulate of various shades. Moisture does not penetrate the granulatory, and with the help of it, bitumen has protection against damage and ultraviolet radiation. Thus, the pattern will be perfectly preserved. The mass of bitumen polymer is glued to the lower part of the tile. Glue has a protection consisting of an easily retiring film.
