Seawall erosion is the leading cause of seawall failure — and it's almost always invisible until the damage is severe. At Seawall Repairs by Solid Foundations, we specialize in diagnosing and stopping erosion behind, beneath, and around your seawall before it reaches catastrophic failure. Our non-invasive erosion control methods preserve your existing structure and cost a fraction of full replacement.
Seawall erosion occurs when the soil or fill material behind the seawall panel is displaced by water intrusion. Water enters through panel cracks, joint gaps, or around the toe of the wall, carrying fill material outward with each tidal cycle. Over time, this creates voids — empty spaces behind the panel — that allow the wall to crack, tilt, and eventually collapse. Erosion control means sealing the entry points and refilling the voids before structural failure occurs.
We inspect the wall visually from both land and water sides, use a probe rod to test for voids, and assess the soil conditions along the base.
We identify the location and extent of voids behind the panel using probe testing and, on larger projects, ground-penetrating radar.
All cracks, joint gaps, and toe openings are sealed with compatible materials — preventing further water intrusion.
NCFI-certified polyurethane foam is injected through the panel into all identified voids. The foam expands, fills the void completely, and cures to a rigid, waterproof mass.
Where hydrostatic pressure is contributing to erosion, we install relief drains to equalize pressure and prevent future erosion events.
We re-probe all treated areas to confirm complete void fill and provide a written report of all work performed.
Seawall erosion control typically costs $80–$300 per linear foot depending on void depth and extent, fill material needed, and wall accessibility. A typical 80-foot residential seawall erosion repair runs $5,000–$18,000. This compares to $30,000–$80,000 for full seawall replacement.
