Basement & Cellar Tanking

Areas of wall below ground level will be affected by lateral damp penetration and therefore it is essential a waterproof coating be applied to the internal wall surfaces. This can be achieved by multi-coat waterproof renders or ventilated membrane systems.

Ventilated membrane systems are used where there is as high risk of water ingress into the basement. This allows water to enter the building under controlled conditions, behind the studded membrane into a purpose formed channel, which is drained into a sump and is then pumped out of the building.

Make the most of your property's natural assets and convert that unused basement or vault into a beautiful space. Scroll down to view before and after stages of typical dank & damp basement converted into habitable space.
