Cavity Drain membranes provide an air gap between the membrane and the wall, which allows any free water to run behind it. The membrane is mechanically fixed to the original sound wall surfaces then overlaid with treated battens or other framing systems, on to which plasterboard can be fixed.
In some cases the battens can be ommited and plasterboard and membrane fixed using special plastic plugs, alternatively a wet plaster could be applied.
