Chemical Bund, Wales

An incorrectly specified bitumen material was installed in this chemical bund. The material failed after being exposed to chemicals used in UPVC door manufacturing. Koster Aquatecnic Ltd were asked to provide a solution.

The surface was mechanically prepared, removing the failed bitumen coating and repairs were carried out to the area.

Due to the risk of ground water penetration, a negative side tanking system was installed. Koster NB1 Grey was applied to the walls and floor area of the bund before Koster SL Premium was used to provide a strong level surface to accept the Koster LF-VL coating on the floor. Koster EM-VS was applied on the upstands.
