Tanking is a general building term for coating, or lining, walls underground to seal them against water, hence the idea of forming a complete tank. To really qualify as tanking all the below-ground walls and floors have to be coated or lined. Tanking materials, liquid or membranes can be applied to the inside of the building or the outside. All new build structures below regulations can require tanking and buildings regulations can apply when tanking existing buildings.
Tanking existing buildings to prevent water from entering basements and sellers can be carried out with liquids or lining membranes that may also involve drainage or sometimes a pump and sump method.
