HydraDry WaterStop – Rapid-Setting Leak Plugging & Repair Mortar

HydraDry WaterStop is a fast-acting, expanding mortar, specifically designed to stop active water leaks and seepage in concrete and masonry. Upon application, it expands as it sets, creating a permanent watertight seal with concrete-like strength once cured.

Ideal Applications:
