Waterstop RX

An active sodium bentonite based waterstop that is designed to replace conventional passive PVC dumbbell waterstops, thus eliminating the requirement of split-forming and product seam welding.

Waterstop-RX is a flexible strip concrete construction joint waterstop that provides a permanent seal by expanding upon contact with water. Waterstop-RX is an active sodium bentonite based waterstop that is designed to replace conventional passive PVC dumbbell waterstops, thus eliminating the requirement of split-forming and product seam welding.

Waterstop-RX is manufactured in lightweight, flexible coils that can be installed in both hot and cold weather. The product is adhered to concrete, steel, and PVC (pipes) with CETSEAL; at or exceeding the required minimum distance from the exterior concrete surface.

The key to Waterstop-RX is sodium bentonite. Sodium bentonite swells when in contact with water, forming an impermeable barrier. This swelling property allows Waterstop-RX to form a permanent pressure seal within the concrete joint, thus eliminating water migration over or along the waterstop. In addition to forming a positive pressure seal, the product’s expansion properties allow it to seal small cracks and void areas. Waterstop-RX has been successfully tested by independent testing firms to over 60 meters (200 feet) of hydrostatic water pressure under both continuous emersion and wet/dry cycling.

General Applications

Waterstop-RX applications include both vertical and horizontal concrete construction joints, new-to-existing construction, irregular surfaces, and around throughwall penetrations, such as plumbing and electrical conduit. Waterstop-RX is designed for both hydrostatic and non-hydrostatic conditions. Waterstop-RX is not designed, nor intended to function as an expansion joint sealant. Contact manufacturer for precast concrete applications, technical information and approval.

Waterstop-RX is designed for structural concrete with a minimum of 3000 psi. 101 and 101T, require a minimum 75 mm (3”) of concrete coverage. Waterstop-RX 102 requires a minimum concrete coverage of 50 mm (2”).
