What Causes Seawall Damage in St. Augustine
St. Augustine's seawalls take a steady beating from tidal swings on the Matanzas River, boat wake along the Intracoastal Waterway, and the storm surge that comes with coastal Florida hurricane season. That pressure works soil loose from behind a wall over time, and a small crack can widen into a structural problem.
How We Fix It
We repair most failing seawalls with Targeted Grout Injection — pumping a hydrophobic polyurethane resin called 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 potable water, and meets Florida DOT specifications for chemical grout injection of soil. Caught early, this is a far less invasive and less expensive fix than tearing out and replacing the wall.
