RIW Waterstop is a hydrophilic waterstop, a sodium bentonite based material, designed to stop water infiltration through insitu concrete construction joints. Sodium bentonite swells when in contact with water, forming an impermeable barrier. The swelling property allows the RIW Waterstop repairs to form a permanent pressure seal within the concrete joint, thus eliminating water migration over or along the waterstop.
