Seawalls

Why Do Seawalls Fail?

Seawalls protect your property from erosion—but they take constant abuse from water, waves, and changing soil conditions. Over time, that takes a toll.

Common causes of seawall failure include:

• Water seeping through cracks and joints, eroding soil behind the wall
• Hydrostatic pressure building up and pushing the wall outward
• Soil loss creating voids behind the seawall
• Age and wear weakening the structure

Left untreated, voids grow larger. The wall leans or bows. Sections start to fail. And what could have been a repair becomes a full replacement.

The Fix: Seawall Stabilization

We use polyurethane foam injection to fill voids behind the seawall, seal cracks and joints, and stabilize the surrounding soil. This stops erosion, relieves pressure, and extends the life of your existing wall.

• Fills voids behind the seawall
• Seals cracks to stop water infiltration
• Stabilizes soil to prevent further erosion
• Relieves hydrostatic pressure pushing against the wall
• Extends seawall life without full replacement

Signs Your Seawall Needs Attention

• Visible leaning or bowing
• Cracks or separating joints
• Soil sinkholes or settling near the wall
• Water seeping through the wall
• Loss of soil or landscaping behind the seawall

Seawall problems don’t fix themselves—and the longer you wait, the more expensive the repair. If you’re seeing any of these signs, it’s time to get an estimate.
