Waterprooﬁng in the bathroom

Don't give moisture a chance: with Schlüter-KERDI

Although tiles are generally impervious to water, the fact that moisture can reach the substrate through the joints is frequently overlooked. To prevent mould and damage to the building structure, continuous and dependable waterproofing must be applied to bathroom floors and walls before the tiles are installed.
