Waterstop-RX is a sodium bentonite based waterstop designed to stop water infiltration through cast-in-place concrete construction joints by expanding upon contact with water to form a positive seal against the concrete. The key toWaterstop-RX’s effectiveness is its high sodium bentonite content which provides superior expansion to seal and fill voids and cracks in the concrete. Waterstop-RX is an active bentonite/ butyl-rubber based waterstop that is designed to replace passive PVC/Rubber dumbbell waterstops, thereby eliminating the requirement of special pieces, split-forming and seam welding. Waterstop-RX has been successfully tested by independent testing firms to over 200 feet (60 meters) of hydrostatic water pressure, under both continuous immersion and wet/dry cycling.

Uses & Features

• Proven effective on projects worldwide for more than 20 years.

• Can expand several times its volume to fill voids.

• Seals pipe penetrations that PVC waterstops cannot effeiciently seal.

• Ends naturally join together to form one continuous waterstop.

• Proven effective in structures under continuous or intermittent

hydrostatic pressure.
