Superstop is a composite waterstop containing expandable, granular bentonite. One edge is layered with a pressure sensitive adhesive.
Tremco recommends SuperStop as a waterstop for sealing cold joints. The best placement for Superstop is 2” (50mm) inboard from the exterior side of the wall assembly and immediately prior to the rebar caging. If placing in a keyway, it must be clean, smooth and continuous such that the SuperStop may be applied flat and have good contact with the footer or wall.
