A waterproof concrete basement has been constructed to the rear of a London police station. The basement is to be used as a car park and plant room. The basement is of steel sheet piled construction, with the concrete liner walls and floor made watertight by the inclusion of Triton’s TT Super Admix within the RC structure. Triton’s TT Waterstop and TT Swellseal Mastic were used to waterproof all concrete construction joints interfaces, and penetrations, such as service ducts / tie bars etc.

The ground level slab incorporates a minimum 1M band of concrete waterproofed with TT Super Admix around the entire perimeter and this external podium detail will be further waterproofed at a later stage using Triton’s TT Vapour Membrane and Platon Double Drain membrane.

• 2000 kg Triton TT Super Admix
