Waterproofing

Waterproofing

Cavity drain membranes provide an alternative to conventional cementitious tanking systems, which work by holding the water back. Cavity drain membranes work on the principle of allowing water to continue to penetrate the structure but control it in the air gap and divert it to a suitable drainage point. They do not allow pressure to build up against the internal construction and the air gap behind the membrane allows the structure to breathe and to some extent to dry out.

The membranes are loosely laid on floors and fixed to walls using special plugs and sealing materials. Once the membrane has been fitted, wall surfaces can be dry lined or plastered directly and floors can be screeded or a floating dry board system installed.

Any water collected by the drainage system is collected in a hidden sump with 2 no. pumps the water is then pumped up and out of the basement. The pumps are incrediably reliable and have back up safety systems with integrated alarms and even options to call your phone if there is a problem. Ensuring your basement is dry at all times.
