Tanking a basement or cellar

basement tankingTanking a basement is the method of damp proofing in basements. Tanking is a generic name given to the process of waterproofing below ground walls and may refer to either one wall, a part of a wall or an entire basement, whereby a ‘tank’ is created to hold back water.

Tanking is a special waterproof cement slurry which is applied to the walls / floors. Prior to treatment, the existing surface coatings require removal such as existing plasters, paint and any old coatings such a bitumen etc.

These are usually removed using chiselling machines and surface preparation tools such as scabblers, scourers and needle gunning. Alternatives some brick / concrete surfaces may be prepared by sand  or grit blasting.

Remove wall and floor coatings

Basement waterproofingHaving removed the coatings, the walls are made good by filling of any voids etc using concrete renders. The walls are then treated by the multi coat application of tanking cement which is applied either by brush, spray or trowel.

Where walls and floors join a fillet strip may be installed and the tanking extended on to the concrete floor. Floors can then be screeded with a waterproof screed and the walls replastered using a waterproof render system such a Kenwood Waterproof render.

Tanking is an effective barrier for waterproofing basement and when installed by specialists, can provide a guaranteed solution to water ingress.
