In most cases, yes. What we want to know first is whether the wall is still straight and its panels or sheets are whole. If they are, the problem lives in the joints, the cap, or the soil behind the wall, and those are repairable.
Look along your wall on a falling tide for:
A straight wall with a few of these is a repair job. A wall that has tipped or broken through belongs on bulkhead replacement in Jacksonville.
The St. Johns is tidal a long way inland. The UNF State of the River report says the tide reaches as far as Lake George, 106 miles upstream, and that tidal flow is about seven times the river's freshwater discharge (UNF). Water pushes in and drains out of every open joint twice a day, and each cycle carries a little more soil out.
Near the mouth at Mayport, the daily range is close to 5 feet on NOAA's datums. At the Buckman Bridge it's closer to 1 foot. A wall near the coast sees much bigger swings, while a wall upriver may spend more time with steady water against it. We read your wall in light of where it sits.
During Irma, salinity at downtown Jacksonville jumped from under 5 parts per thousand to about 30, close to seawater, according to the Hurricane Center. Salt reaching steel reinforcing and tie rods speeds up rust.
Busy stretches of the Intracoastal and the Ortega River send wake against walls all day, working at weak joints.
We inject NCFI-certified polyurethane through small ports behind the wall to fill hollows, bind loose soil, and seal joints from the back. Your yard stays in place. Details on polyurethane injection.
Cracks are sealed, and broken cap sections are cut back, the steel treated, and the cap re-formed.
Rain trapped behind a wall adds pressure. Relief drains let it out.

Structural work generally needs a building permit from the City of Jacksonville's Building Inspection Division (City of Jacksonville). Atlantic Beach, Neptune Beach and Jacksonville Beach run their own city governments, so addresses there go through those cities. We handle the paperwork. See our Jacksonville seawall repair page for the rest of what we do locally. We also repair bulkheads up the coast in St. Simons Island.
It usually means soil is washing out through a joint or crack. Left alone, it becomes a hole in your yard. Void fill and joint sealing typically fix it.
Tides near the mouth swing about five feet a day, much more than upriver. Bigger swings pump more water through any gap.
Usually. Most repair work happens from the land side or through small holes, so the dock can stay put.
No. Jacksonville Beach, Neptune Beach and Atlantic Beach have their own city governments and permitting. We work with whichever applies.
