Home / Resources / Six signs your seawall needs attention

Seawalls usually warn you before they fail. Catch these signs early and a repair often beats a full replacement.

Why early matters

A seawall that's caught early can often be repaired or reinforced. Left alone, the same problem can undermine the wall, take your backyard with it, and turn a repair into a full replacement. These are the signs worth acting on.

What to watch for

1. Cracks in the cap or panels

Hairline cracks are common, but widening cracks, spalling concrete, or exposed steel signal that water and salt are reaching the structure.

2. The wall is leaning or bowing

A wall tilting toward the water usually means soil pressure behind it is winning, often because tiebacks have failed or drainage is poor.

3. Soil loss or sinkholes behind the wall

Depressions, voids, or disappearing soil behind the cap mean fill is washing out through the wall — a clear warning sign.

4. Rust stains and weeping

Rust streaks point to corroding reinforcement; constant weeping can mean the drainage system behind the wall is clogged or failed.

5. Gaps at the joints

Separating panels or open joints let backfill escape and let water work behind the wall.

6. Scour at the base

Erosion at the toe of the wall undermines the whole structure and is a leading cause of failure.
