WATERSTOP-RX® Expanding Concrete Joint Waterstop
Unmatched Protection for Concrete Joints
WATERSTOP-RX® is one of the most efficient and effective waterproofing products available today for preventing water penetration in concrete joints.
There’s nothing else like it.
Low-cost enhancement for improved external waterproofing
For cast-in-place, reinforced concrete structural joints—vertical and horizontal—as well as around pipes and structural penetrations, WATERSTOP-RX® is your most reliable protection against water. Working as an active barrier for structures under either continuous or intermittent hydrostatic pressure, WATERSTOP-RX® substantially reduces the possibility for leaks—its active volcanic bentonite component absorbs up to 15x its volume in water, expanding to seal cracks using the very pressure of the water itself to fill and block any gaps.
WATERSTOP-RX® is available in three size/shape configurations for effective fit in nearly any appropriate construction gap:

Easy installation saves you money
WATERSTOP-RX® is also easy on your budget, saving you money in time and installation. Designed for greater performance predictability, it replaces traditional PVC/Rubber dumbbell waterstops, eliminating the need for special pieces, split-forming, and seams. WATERSTOP-RX® is manufactured in lightweight, flexible coils and can be easily installed by a single worker without extensive training—Simply apply WATERSTOP-RX® to a prepared surface and press it into place.
How it does it
WATERSTOP-RX® features an active bentonite/butyl-rubber construction and has been successfully tested by independent testing firms to over 60 meters (200 feet) of hydrostatic water pressure, under both continuous immersion and wet/dry cycling.
