Expanding Concrete Waterstop
Waterstop-Rx® is a bentonite and butyl rubber-based waterstop designed for concrete construction joints in both hydrostatic and non-hydrostatic conditions. Upon hydration, Waterstop-Rx® swells to form a positive pressure seal that locks out water and prevents migration in concrete joints. Waterstop-Rx® is proven effective when exposed to over 200 feet (60 metres) of hydrostatic pressure.
