What Causes Seawall Damage in Sebastian
Sebastian's location where the St. Sebastian River meets the Indian River Lagoon means seawalls here face daily tidal exchange, brackish water, and boat wake from the lagoon. That combination is what wears down joints and washes soil out from behind a wall over time.
How We Fix It
When the damage is caught early, we repair with Targeted Grout Injection instead of a full replacement. We pump a hydrophobic polyurethane resin — Prime Flex 910 — through a 3/8" port to seal leaks and fill the voids that have opened up behind the wall. The resin cures underwater, is NSF/ANSI certified for use around water, and meets Florida DOT specifications for chemical grout injection of soil. It's a faster, less invasive, and less expensive fix than tearing out and rebuilding, when the wall's structure is still sound.
