Waterproof Membranes for Walls

A modern alternative to cementitious tanking

What is a waterproof membrane?

A waterproof membrane (often called a cavity wall membrane) is an internally applied damp wall solution that works by managing and controlling water ingress within a gap formed between the cavity wall membrane and the basement or cellar wall. It then directs water to a suitable drainage system and/or sump pump. This is completely different to traditional tanking that works by holding back any water ingress with a layer of cement or slurry.

The advantages of waterproof membranes

Our waterproof membranes are straightforward to install, flexible, easily maintained and is supported by our 10-year waterproofing guarantee.

Unlike more traditional forms of wall waterproofing, it is not susceptible to cracking under the strain of external hydrostatic pressure. It is also unlikely to be effected by ground vibrations from nearby roads or rail tracks.

Best of all, if you are planning on making your basement or cellar look as welcoming as any other room in the house, waterproof membranes can be dry lined or have plaster applied directly onto it, making it an ideal solution for a domestic basement conversion.

An alternative to tanking?

Wise Basement Systems often find ourselves recommending a damp wall system using waterproof membranes when a cementitious tanking system fails. To give you an idea why...check out the video below.
