Superstop is a composite waterstop containing expandable, granular bentonite. One edge is layered with a pressure sensitive adhesive.

Superstop is used for sealing cold joints in concrete, to create water dams under roofing membranes, to create water dams under floor membranes and to prevent water migration through construction joints. Properly installed, Superstop will stop the passage of water through a static cold joint or between two abutting impermeable surfaces. Superstop is also available in saltwater grade for use in approved brackish water conditions.
