Six Signs Your Seawall Is in Trouble

Ranked by Urgency

1. Sinkholes or soft spots behind the wall

Backfill escaping through the wall below the waterline; the surface dimple understates the cavity. Rope it off and get eyes on it fast.

2. A visible lean

Sight down the wall from a corner. Lean means tiebacks or toe support failing — and on original mid-century walls the anchors are usually the first thing spent. Early is anchors; late is a new wall.

3. Cap cracks that catch a fingernail

Saltwater’s doorway to the reinforcing steel; repair costs multiply roughly tenfold once the steel corrodes, and 60-year-old steel has no margin left.

4. Rust bleed-through

Orange streaks mean corrosion is already running inside the panel.

5. Daylight or jetting water at joints

Open joints are how canals eat backyards — most visible on a falling tide.

6. Standing water behind the wall

Blocked weep holes trap hydrostatic pressure — the force that pushes walls over, and the condition surge events leave behind. More in the storm guide.

Found One? Found Three?

One sign: photograph it with a date and watch it. Multiple signs — especially lean plus soil loss on an original wall — is inspection time. Ballpark the fix, then call (727) 353-9179.
