Tanking/waterproofing

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 favorable to penetrating dampness and water ingress via capillarity and/or hydro static pressure.

In order to waterproof underground structures and convert them into habitable and functional basement accommodation 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. The two most common wall tanking methods for waterproofing basement walls are:

Cavity Drain Tanking Membrane - Robust dimpled waterproofing membranes that can be applied to almost all underground building structures that are affected by penetrating damp or water ingress. The impervious studded membrane creates continuous air cavities to permit ample water drainage and air circulation, allowing underlying substrate to both drain and breath. Fully sealed waterproof basement membranes enable water ingress management via the provision of sump and pump systems to ensure water is channelled, drained and discharged from the building.

Structural Waterproofing - This is multi-coat, pore-blocking slurry mix, the tanking slurry contains polymers designed to enhance adhesion to the wall and increase tensile strength. Once applied the tanking is able to withstand external water pressure and maintain a dry environment by creating a physical barrier to water entering the basement area through the walls.
