Volclay Waterstop-RX

Please call for quote on other styles and sizes.

Volclay Waterstop RX® is a flexible strip concrete construction joint sealant that provides a permanent watertight seal by expanding upon contract with water. Waterstop RX® is an active Bentonite/ Butyl rubber-based waterstop that is designed to replace conventional passive PVC dumbbell waterstops, thus eliminating the requirement of split-forming and product seam welding.

Applications include both vertical and horizontal concrete construction joints, new to existing construction, irregular surfaces, and around through-wall penetrations, such as plumbing and electrical conduit.

Waterstop-RX is designed for both hydrostatic and non-hydrostatic conditions. However, Waterstop RX® is not designed, nor intended to function as an expansion joint sealant. 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 Volclay WB-adhesive at or exceeding the required minimum distance from the exterior concrete surface.

Coil ends are butted together (not overlapped) to form a continuous waterstop. In most applications, Waterstop RX® is installed to the interior side of the outer row of steel reinforcement to allow for sufficient concrete coverage.

Waterstop RX® should only be used in applications where the product is completely encapsulated within the concrete.
