Seawalls crack and leak over time - and that water washes soil out from behind the wall. Our non-intrusive injection system seals leaks and stabilizes soil from the land side, often in one day, for a fraction of the cost of full replacement.

When we repair your seawall, the goal isn’t just “stop the leak you can see.” It’s to protect your shoreline and stabilize the soil behind the wall for years. That’s why residential Sealtite seawall repairs come with our Sealed-for-Life Guarantee - built around sealing leaks and reinforcing the areas where erosion starts.
Seawall damage begins with water movement through cracks and joints, which can wash out soil behind the wall and create hidden voids before the surface looks “bad.” We focus on the root cause so the problem doesn’t keep coming back.
A leaking seawall isn’t just “a little crack.” When water moves through the wall, it can wash soil out from behind it, creating hidden voids that lead to sinking ground, unstable caps, and shoreline loss over time. Even if the wall still looks "okay" from a distance, the damage often starts behind the scenes - and it can get expensive fast if it’s ignored.
The bigger issue is what happens next. Once erosion begins, it rarely stops on its own: voids grow, leaks worsen, and every heavy rain or high-water event can pull more soil out from where you need it most. That can affect your yard, your dock area, your pool deck, and any concrete or structures sitting near the wall.
Seawall repair is the fastest way to stabilize the soil, stop the washout, and protect your property without the cost of full replacement.
High-density polyurethane is designed to flow into voids and then cure into a rigid, water-resistant mass that helps seal leaks and stabilize the soil behind the wall It’s a reinforced fix, not just a “patch.” Cured material commonly lands in the 50–150+ PSI range, which translates to thousands of pounds per square foot of support. A strong, stable backing when installed correctly.

Warranty Rate Shows Quality of Work
If an area we repair starts leaking again through the same sealed crack/joint while you own the home, Sealtite will re-seal that same area one time at no cost, as long as Sealtite performed the original sealing/stabilization work and normal drainage, backfill are weep holes are maintained around the seawall. This guarantee is not covered when leakage or washout is caused by flooding/acts of God, ongoing water issues, impact damage, or movement from structural failure outside the treated area, and it does not include cosmetic concrete repair or unrelated crack restoration.
Commercial, industrial, and municipal seawall work includes a 10-year warranty.
We spell out exactly what’s covered (and what isn’t) and we tie our guarantee to proven conditions that protect your property, like proper sealing, stable soil, and good drainage. That means you get a seawall repair that’s designed to hold up, plus a warranty that’s fair, enforceable & backed by a team willing to put it in writing and stand behind the work.
