Cavity Wall Insulation Extraction Experts based in Lancashire

Cavity Extraction Ltd uses a studded polypropylene waterproofing membrane with a mesh welding to one side. It can be fixed directly to the damp / contaminated substrate using plaster plugs with the stud faced side of the membrane to the wall. This creates an air gap allowing air flow so the substrate can breathe whilst blocking the passage / ingress of moisture.

On the outer facing surface of the membrane is a meshed finish which can be plastered directly on to or if you choose you can dot and dab plaster boards with a finishing skim allowing a dry plastered finish to be achieved with no risk of contamination from damp or hydroscopic salts from within the wall.
