Aquaproof 121

Cementitious Membranes

Aquaproof 121

Aquaproof 121 is a unique flexible one component waterproof membrane that is suitable for a wide range of positive and negative waterproofing applications.

Based on advanced cross linking polymer technology, Aquaproof 121 is a standalone flexible polymer cementitous membrane that does not require the addition of any liquid additive, requiring only water added to powder to form a high quality liquid membrane slurry system. Ideally suited over concrete, masonry and mineral substrates. The cured film provides a water tight membrane that is permeable to vapour diffusion and offers excellent resistance to frost and ageing, as well as outstanding adhesion properties.
