The Tremco 1/2 in. x 1 in. x 20 ft. Superstop Waterstop (10-Pack) is a composite waterstop containing expandable, granular bentonite. One edge is layered with a pressure sensitive adhesive. The superstop is used for sealing cold joints in concrete and to prevent water migration through construction joints below grade. Properly installed under compaction, Superstop will stop the passage of water through a static cold joint or between two abutting impermeable surfaces.
