Superstop is a water swelling and resealable waterstop material which forms an effective, permanent seal. When water comes into contact with Superstop, the bentonite clay expands to form an impenetrable barrier which seals against further fluid migration. One edge is layered with a pressure-sensitive adhesive. Superstop eliminates need for splicing, seaming and split form construction techniques.
Superstop is available in 13mm (1/2") thickness and 19mm (3/4") thickness.
