Supercast SW range consists of swellable waterstops; Supercast SW formed sections, Supercast SWX gun-applied paste and Supercast SW Adhesive. Expansion of the waterstop creates a positive pressure against the faces of the concrete joint, thus preventing water passing through the joint. Supercast SW waterstops are high performance products with excellent long term durability through wet/dry cycling and can withstand 1bar water pressure after 1 day cast in concrete.
