Waterproofing Damp and Wet Rooms (Bathrooms & Kitchens)

Waterproofing is applied to both walls and floors of damp and wet rooms as essential for their long-term usability. Details pertaining to the requirements for design and execution and waterproofing materials are found in DIN 18,534 “Waterproofing for indoor applications” that took effect in July 2017.

Holderchem provides long-lasting solutions for waterproofing and protection against water infiltration, of damp and wet rooms, for both new build and renovation projects. The recommended solutions depend on the water exposure classes and crack classes substrates encounter. It is essential to ensure substrates remain dry and free from water damage particularly as many grouting materials are not waterproof nor do they offer, if waterproof, sufficient protection from water ingress.

Holderchem supplies ready to use floor screed for laying ceramic tiles and parquet. Substrates on which the waterproofing system is applied should under normal circumstances withstand stresses caused by the movement of the building, being exposed to water and temperature fluctuations, and the alkalinity of concrete and mortar.
