Tanking is the creation of a watertight envelope as it must be assumed that water pressure will come to bear upon the structure at some point in its life. Therefore with any below ground or retaining structure, tanking should be applied to all surfaces below ground level, and ideally linked in with an effective damp proof course above ground level in order to achieve a continuous system.

The term ‘Tanking’ refers to the application of a bonded membrane to a substrate, which will prevent the passage of ground water.

Tanking systems are applied to either the positive side or negative side of a substrate.
Positive tanking is achieved when the hydrostatic water pressure is pushing the tanking onto the substrate and is generally used in new build situations.

Negative tanking is where the tanking system is applied to the other side of a wall and the hydrostatic water pressure will try to push the tanking off the substrate. This approach is generally used in existing basements and complies with the requirements of BS 8102. Successful Tanking on the negative side requires a comprehensive specification, as supplied by Dampshield in conjunction with Sovereign Chemicals.
