Waterstop-RX is a flexible strip-concrete construction-joint waterstop that provides a positive seal by expanding upon contact with water. Waterstop-RX is an active waterstop that functionally replaces conventional passive PVC dumbbell waterstops. Waterstop-RX is designed for both continuous and intermittent hydrostatic conditions and has been
successfully tested to resist 231 feet (70 m) of hydrostatic pressure. The key to the effectiveness of Waterstop-RX is its 75% sodium bentonite content which provides superior expansion to seal cracks and fill small voids. Proven effective on projects worldwide for over 20 years, Waterstop-RX is a reliable and cost-effective solution to preventing water
infiltration through concrete joints. Waterstop- RX offers a low cost opportunity to enhance the performance of a solid external waterproofing system, by sealing the areas of highest likelihood of water infiltration through the concrete, and should therefore be implemented as part of the waterproofing design.
