This process involves attaching layers of high density polyethylene extruded membrane to the walls, ceilings and floors of the basement. Minimal preparation is needed, making this method a quick and cost-effective way to protect your basement from damp problems and to make it an adequate living environment. This option is considered a water management system as it still allows moisture into the space, but it feeds the water into drainage channels where it is pumped safely away. Plastering can be applied directly to the membrane walls or dry lining can be placed directly onto battens.
