How do you waterproof a terrace?

Patio waterproofing protects the structure underneath from water ingress. The waterproofing sits on the structural layer – beneath your floor finish – and you must have adequate fall for water to drain away.

Apply ALLESDICHT as a liquid coating directly onto the prepared substrate. Concrete, screed, old tile or bitumen all work well. The advantage on a patio is that the seamless coating seals tightly where the house wall meets the slab, at door thresholds and around drains – exactly the weak points where sheet systems often fail. Apply two or three coats to achieve a minimum dry thickness of 2 mm. The coating’s flexibility bridges small cracks in the substrate beneath.

Once it’s fully cured, you can lay your chosen floor finish straight on top – rubber tiles, ceramic tiles or a further coating.
