The Ideal Internal Wall for Basement Conversions
The cavity membrane allows for better air flow, so no condensation can occur. The surface of the wall can be decorated immediately, and electric cables, plumbing pipes, etc. can be concealed within the wall. The cavity membrane is resistant to cracks, vibration and building movement, and is carries a 20-year guarantee.
The Cavity Drainage Membrane can be installed on walls, ceilings and floors using waterproof sealing plugs, battens and plasterboard and then skimmed with finish plaster allowing you to decorate your basement conversion to suit your intended use.
Floor areas are finished with tongue and groove pre-treated boards or stone slab, raised between approximately 30mm-60mm depending on the type of flooring specified by the surveyor. This is essential to allow constant moisture to evaporate behind the H.D.P.E membrane.
