What are the warning signs you need seawall repair?
- Sinkholes, divots or soft spots in the yard within 10 ft of the wall
- Rust staining and spalling along the seawall cap
- Panels leaning waterward more than 1 inch out of plumb
- Visible daylight or soil washing through panel joints at low tide
How the work is actually done
- 1
Dive & dry inspection
Panel-by-panel survey above and below the waterline, plus a plumb check on every joint.
- 2
Void mapping
Probe rods locate soil loss behind the wall so grout volume is quoted, not guessed.
- 3
Injection & sealing
Hydrophobic polyurethane stops active water movement, then structural grout fills the void.
- 4
Cap & joint restoration
Spalled cap sections are chipped to sound concrete and rebuilt with a marine-grade repair mortar.

Questions
Seawall Repair FAQs
How much does seawall repair cost?
Most Tampa Bay residential seawall repairs run $180 to $420 per linear foot. A typical 75-foot residential wall with two failing panels and moderate soil loss lands between $9,000 and $18,000 fully permitted.
Can a leaning seawall be repaired instead of replaced?
Yes, if the panels are less than roughly 3 inches out of plumb and the cap is intact. Beyond that, tieback anchors have usually failed and replacement is the cost-effective path.
Do I need a permit to repair a seawall in Hillsborough County?
Repairs in kind typically require a county shoreline permit, and work waterward of the mean high water line also needs a Florida DEP or SWFWMD authorization. Your contractor should pull both.
