Waterproofing mortars are used to protect structures against water infiltration. They are supplied as ready-to-use solutions to seal against damp soil, seepage and percolating water. Waterproofing mortars are often applied in water reservoirs, water retaining structures, basements and other engineering structures as well as beneath tiling for swimming pools, balconies, bathrooms and kitchens.
