Is Your Seawall Failing?

Failing Seawall

Owning waterfront property in Texas—whether along the Gulf Coast, Clear Lake, Galveston Bay, Lake Conroe, or the Intracoastal Waterway—means enjoying beautiful views and easy access to the water. But it also means maintaining one of the most important protective structures on your property: your seawall.

At Cajun Marine Construction, we regularly help Texas property owners address seawall damage caused by storms, tides, erosion, and aging materials. Most seawall failures start small, then suddenly worsen—leading to rapid land loss and costly repairs.

If you’re starting to notice changes around your seawall, here are the warning signs and what they mean.

Common Signs Your Seawall Is Failing

1. Soil Loss or Sinkholes Behind the Wall

Soft spots, depressions, or holes forming behind the wall indicate water is leaking through or underneath. This erosion can eventually trigger a full collapse.

2. Cracks or Separation in Concrete Panels

Texas heat, soil movement, and tidal action cause cracks to expand over time. Separation between panels is a major structural concern that needs immediate attention.

3. Leaning or Bowing

A straight seawall should remain vertical. Leaning toward the water—or toward your property—is a sign the structure is being pushed beyond its capacity.

4. Corrosion or Rust Staining

Steel tie-backs, anchors, and rebar can corrode in brackish or saltwater environments. Rust streaks often signal internal damage.

5. Water Weeping Through the Wall

Some drainage is normal, but continuous water flow indicates pressure buildup behind the wall. This can lead to blowouts or major panel failure.

Why Texas Seawalls Fail

Texas coastal and lakeside conditions can be harsh on marine structures. Common causes include:

• Wave action from the Gulf and heavy boat traffic

• Storm surges and hurricanes

• Expansive Texas soils that shift with moisture changes

• Saltwater corrosion

• Aging or outdated construction methods

• Improper or clogged drainage systems

These factors accelerate erosion and shorten the lifespan of any seawall.
