Tanking

Tanking is the term often used when referring to the process of waterproofing a basement or cellar. This is achieved by the application of a completely waterproof layer (tanking coating) over the basement wall and floor surfaces.

Basement conversions are becoming increasingly popular as people strive to increase and improve their living spaces. Tanking is used to prevent the ingress of water into the basement space and to prevent the damage that can result from such damp, including structural damage, mould growth and timber rot. Tanking allows a damp cold space to be turned into a safe, habitable environment.

The way that tanking systems work is by providing a waterproof coating directly to the inside of the walls/floors to prevent moisture ingress. Tanking a surface does not remove the water, it simply creates a barrier.

Tanking products can be applied using a trowel or can sometimes be sprayed on. Plaster can then be applied on top of the tanking coatings. Attention must also be applied to weak points in the structure (i.e. wall/floor junctions) where water is most likely to enter.

Basement tanking products and their installation must be carried out according to the code of practice BS:8102 which details how underground structures should be protected from water ingress. SkilledBuild’s tanking products are manufactured to the highest standards and comply with relevant guidelines.
