The Aquaproof System has been developed to prevent water leakage from tiled areas, including wetrooms, shower areas, bathrooms and kitchens.


Once applied, the Aquaproof System can tolerate normal levels of movement in a room and does not become brittle with age. It is technically-advanced and comes with a 10-year manufacturer’s warranty; it is independently-certified as meeting the requirements of ETAG 22 'watertight covering kits for wetroom floors and walls' and holds its own European Technical Approval certificate. 


By specifying Aquaproof, a fully-tanked room can be achieved, preventing damage to walls/ floors, and leakage into adjacent rooms.
