Many buildings contain uninhabitable, mouldy and damp basement walls with no waterproofing protection. Cellar walls, which typically form the foundation of the building, are generally sited underground, beneath the waterproof membrane layer that serves as the buildings damp proof course. Accordingly the wall is constantly subject to conditions favourable to penetrating dampness and water ingress via capillarity and/or hydrostatic pressure.
In order to waterproof underground structures and convert them into habitable and functional basement accomodation it is necessary to provide a fully sealed basement waterproofing or tanking system to ensure the moisture in the walls and floors is not permitted to migrate to the internal wall surfaces. Such systems are now available to DIY and trade.

The two most common wall tanking methods for waterproofing basement walls are:
