Rubber Waterstop

Rubber Utility Straps

Rubber Waterstop

Rubber Waterstop has been used extensively on projects throughout the United States and the world. Starting with projects designed by the U.S. Army Corps. of Engineers and the U.S. Bureau of Reclamation, Rubber Waterstop usage has expanded to all types of concrete structures for the purpose of keeping liquids in or out. SBR Rubber has been used primarily for water containment, while Neoprene Rubber has been used generally for projects involving sewage, water treatment, and chemical environments. Waterstops are also available in other polymers such as EPDM, Nitrile, Silicone, and Natural Rubber.

Waterstop Profile Chart:

The profiles below are normally provided in SBR and Neoprene compounds as required. Waterstop is usually provided in 50 ft. lengths, but can be manufactured in longer and shorter lengths to minimize field splicing. Special profiles and compounds can be provided to meet specific project requirements. WARCO BILTRITE Rubber Waterstop is also available in non-spec commercial grade.
