Concrete Waterstops

Concrete waterstops are critical components in any structure designed to resist water intrusion. They’re placed at construction or cold joints to block water movement through the concrete, helping maintain the integrity of foundations, tunnels, tanks, and below-grade walls. When properly selected and installed, a waterstop forms a continuous barrier that swells or seals when exposed to moisture, creating long-term protection against leaks and corrosion. Choosing the right type—whether bentonite-based, PVC, or hydrophilic—ensures dependable joint performance and reduces maintenance over the life of the structure.
