Seawall Erosion Repair

Protect Your Shoreline Investment—Before It’s Too Late

Is the ground behind your seawall sinking or caving in? Are sinkholes forming or pavers near the edge becoming uneven? Do you see cracking in the concrete cap or exposed rebar?

As seawalls age, these problems become more and more common—and if left untreated, they can lead to costly structural failure.

Preserve the Barrier That Protects Your Property

Your seawall is more than just a feature—it’s a critical barrier that protects your property from ocean, lake, river, or canal forces. A failing seawall not only puts your land and structures at risk but also drastically lowers your property’s value.

Replacing a 100-foot seawall can cost anywhere from $40,000 to $60,000—or more. But there’s a smarter, more affordable solution.

Seawall Repair That Works—Without the Cost of Replacement

At Polyurethane Specialists, we bring over 35 years of combined experience in repairing seawall erosion and damage. Our expert team uses a proven, multi-step process to restore strength and stability to your existing seawall—at a fraction of the cost of a full replacement.

Our 3-Step Seawall Repair Process

1. Seal Joints & Cracks 
We start by identifying and sealing all cracks and failing joints to prevent further soil loss and stop erosion at the source.

2. Void Filling Behind the Wall 
Next, we inject a lightweight, structural polyurethane resin into the voids behind your seawall. This foam stabilizes the ground without adding excess weight to the already weakened area.

3. Hydrostatic Pressure Relief System
Finally, we install a pressure-relief system that allows trapped water to escape, reducing hydrostatic pressure and prolonging the life of your wall.
