If your property already has a seawall in place, that’s a great first step toward protecting your shoreline. But many homeowners overlook one of the most important parts of that seawall: the cap. Over time, even the strongest seawalls can weaken at the top—where pressure, weather, and use take the most toll. At Hansen Marine Construction, we’ve repaired and replaced countless seawall caps across Central Florida to restore strength, safety, and long-term durability.

What Is a Seawall Cap?

The seawall cap is the horizontal slab at the top of your seawall. It holds everything together, anchors the tie rods in place, and provides a level surface for walking, fencing, or securing docks and lifts. When the cap deteriorates, it compromises the entire structure.

Signs Your Seawall Cap Needs Replacement 🚨

• Visible cracks or crumbling concrete

• Rust stains near tie rod locations

• Uneven or sunken sections

• Exposed rebar or lifting edges

• Soil loss behind the wall

If you notice any of these issues, it’s time to have the cap evaluated before damage spreads to the entire wall.

Why Cap Replacement Is Critical

✅ Maintains Structural Integrity
The cap ties the entire wall together. A failing cap can loosen tie-back rods, which weakens the wall’s ability to resist water pressure and land movement.

✅ Prevents Full Seawall Replacement
A cap replacement is far more affordable and less invasive than rebuilding the entire wall. Timely action can save thousands of dollars.

✅ Supports Add-Ons Like Fencing and Docks
If you have fencing or dock hardware attached to your cap, a cracked or weak surface poses safety risks and limits functionality.

✅ Improves Aesthetics and Safety
A fresh cap gives your seawall a clean, finished look—and removes trip hazards caused by uneven or broken sections.
