Seawall Maintenance Tips to Protect Your Property from Erosion

“Florida loses up to 15 feet of shoreline during major storms.” That stat alone should get any waterfront homeowner’s attention.

Living in Bonita Springs and the greater Southwest Florida area means enjoying beautiful coastal views—but it also means battling constant erosion, saltwater exposure, and rising tides. Your seawall is your property’s first line of defense. Ignore it, and you’re leaving your investment vulnerable.

At Overall Outdoor & Marine Services, we’ve seen firsthand how proper seawall maintenance can extend the life of your waterfront—and how neglect leads to costly repairs. Below, we break down the essentials for protecting your property from erosion with a solid seawall maintenance plan.

Why Seawall Maintenance in Bonita Springs Matters

Bonita Springs is no stranger to storms, tides, or intense UV exposure. These environmental pressures weaken seawalls over time. Without regular maintenance, even the most well-built seawalls can crack, lean, or collapse.

Benefits of Regular Seawall Maintenance

• Prevent costly structural damage
• Maintain property value
• Ensure compliance with local regulations
• Extend the seawall’s lifespan
• Keep your family and waterfront safe

Common Signs Your Seawall Needs Attention

1. Visible Cracks or Leaning Sections

If you notice that parts of your seawall are starting to bow or crack, don’t wait. These are early signs that the structure is losing integrity.

2. Soil Loss Behind the Wall

Pockets of missing soil or sinkholes near the seawall could indicate water is seeping through—meaning your seawall is no longer doing its job.

3. Rust Stains

Rust stains can be a sign that the rebar inside your concrete seawall is corroding. Once this begins, it’s only a matter of time before structural problems follow.

4. Water Pooling or Drainage Issues

Water that doesn’t drain properly behind the seawall can increase pressure on the structure, causing failure over time.

How to Prevent Seawall Erosion in Florida

Seawall erosion in Florida is a constant battle, but a winnable one if you stay proactive.

Inspect Annually (Or After Every Major Storm)

At a minimum, inspect your seawall once a year. Look for cracks, exposed rebar, soil washout, or algae growth. After a hurricane or tropical storm, do a full checkup as part of your post-storm property inspection.

Maintain Weep Holes

Weep holes allow water behind the seawall to escape. If they’re clogged, pressure builds up and causes cracks. Keeping them clean is a small task that prevents big problems.

Install a Remediation Wall (When Needed)

If your seawall is nearing the end of its lifespan but hasn’t failed yet, a remediation wall—built just outside your existing seawall—can buy you more time and protect your property while you plan a full replacement.

Reinforce with Riprap

Riprap (large stones placed along the base) helps reduce wave energy and protects the wall from further wear. It’s especially useful in areas with heavy boat traffic or strong currents.

Florida Seawall Inspection Checklist

Here’s a simple checklist you (or your contractor) should use during a routine seawall inspection:

• Cracks in concrete or block
• Corroded or exposed rebar
• Soil washout behind the wall
• Misaligned capstones
• Leaning or bowed sections
• Algae or plant growth through joints
• Clogged or missing weep holes
• Signs of undermining (sinkholes, depressions)
• Water staining from reverse seepage
• Loose tie-back rods

Seawall Lifespan and Upkeep Tips

Most concrete seawalls in Florida last between 30–50 years with proper care. However, saltwater, poor drainage, and lack of maintenance can cut that number in half.

How to Maximize Lifespan:

• Schedule bi-annual inspections
• Replace or clean filters in weep holes
• Install drainage systems behind older seawalls
• Keep vegetation trimmed
• Avoid driving heavy equipment near the wall
• Reinforce early with riprap or a remediation wall

When to Call the Experts

It’s tempting to “keep an eye on it” and put off repairs. But that approach often ends with a collapsed seawall and tens of thousands in damage.
