RIW Waterstop

RIW Waterstop is an active bentonite-based hydrophilic waterstop, designed to replace passive PVC/ rubber type waterbars, thereby eliminating the requirement of special pieces and seam welding.

Manufactured in lightweight, flexible coils that are easily installed in hot or cold weather conditions by a single worker.

Has been successfully tested by independent testing firms, to over 70 m of hydrostatic water pressure, under both continuous immersion and wet/ dry cycling.

Application:

• Vertical and horizontal non-moving concrete construction joints.

• New to existing concrete construction.

• Irregular surfaces.

• As a puddle flange around through-wall service penetrations.
