Basement conversions are becoming increasingly popular as a method of increasing the useable space in buildings.

Almost all basement structures are likely to be subjected to water pressure during some period of their life.

Cavity drain membranes work on the principal 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 dry out. The membranes are impermeable to water, gas and water vapour, thus protecting the basement internal space from dampness. The membranes are loose laid on floors and fixed to walls using special plugs and sealing materials.

The membranes can be fitted with little or no preparation to the substrate and once fitted, wall surfaces can be dry lined or plastered directly and floors can be screeded or a suitable dry board system installed.

This method of basement waterproofing allows decoration and floor finishes to be completed almost immediately, without long drying out periods.
