If the surface of the tiles is shiny, then water or special additives was added to the concrete during its production. When arranging a private house, it is necessary to pay close attention to all systems. In particular, all owners of private land are interested in the drainage device, which should be created by all the rules. Drainage is used for land plots, tennis courts and football fields to lay a variety of communications and improve the operational characteristics of the soil. When checking the quality of the tile, slightly hit them against each other. If you feel a ringing sound, then the tile will be of high quality, and if the sound is deaf, then the excess of water is in the tile.
