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 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.
Superstop is also available in saltwater grade for use in approved brackish water conditions.
