Product Description

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. Our High Tensile Neoprene Waterstop provides maximum resistance to Ozone, Sewage, Oil, and Solvents.

We offer a complete line of standard extruded profiles that may be joined using our unique molded intersections. This system provides the flexibility to customize for each application and structure.

Our Cage Code is 06470.

We also offer Cal-Trans Strip Waterstop
