Polyurethane injection fills voids and seals leak paths behind a seawall by injecting expanding resin into the soil. It's a less invasive option when the wall itself is still structurally sound.
It's commonly used in Fort Lauderdale to address sinkholes, limestone voids and soil washing through joints.

Is polyurethane injection a permanent fix?
+
It can be a long-lasting fix for voids and leaks when the wall is structurally sound. It does not repair broken panels, failed tiebacks or an undersized cap.
Void filling vs. replacement: which do I need?
+
Void filling suits walls that are intact but leaking soil. Walls with structural failure or inadequate elevation may need replacement. See our blog guide on this comparison.
