Seawall Repair vs. Replacement: How Do You Know Which You Need?

Nobody wants to replace a seawall they don't have to. Nobody wants to keep paying to patch one that's done either. Here's how to think it through.
Repair Usually Makes Sense When…
- Damage is localized to a few joints, cracks or one section
- The wall is structurally sound and not moving significantly
- The cap is the main problem and the panels are in good shape
- The wall meets or can reasonably meet local elevation requirements
Replacement Usually Makes Sense When…
- Problems keep appearing in new places
- The wall has rotated or displaced significantly
- Corrosion and cracking are widespread
- You need a higher wall than the existing structure can support
- You're planning a new dock or major renovation anyway
The Middle Ground
Seawall stabilization and cap replacement can extend the life of a wall that's aging but not failing. They're often a good bridge while you plan and budget for eventual replacement.
Get the Facts First
The decision should rest on the actual condition of your wall. Start with a seawall inspection, then compare the cost of repair against the cost and lifespan of replacement.
