Protecting Florida Waterfront Properties with Long-Lasting Solutions
Living in Fort Myers, FL, means beautiful waterfront views and coastal breezes—but it also means battling the effects of constant water exposure. Seawalls are essential for protecting properties from erosion and flooding, but over time, they can develop leaks, cracks, and voids behind the wall. If left unaddressed, these small issues can lead to big structural problems.
At Sealtite Slabjacking, we specialize in seawall sealing with polyurethane foam, a fast, effective, and long-lasting solution for restoring structural integrity and preventing further damage.
Why Do Seawalls Leak?
Seawalls are designed to hold back water and prevent erosion, but Florida’s coastal environment puts constant pressure on these structures. Common causes of seawall leaks include:
-
🌊 Hydrostatic pressure from tidal changes
-
🌧️ Heavy rainfall and poor drainage behind the wall
-
🌪️ Storm surges and hurricane impact
-
🧱 Cracks in joints or aging concrete
-
🕳️ Voids behind the seawall due to soil washout
Over time, water seeps through cracks or penetrates behind the wall, washing away supporting soils and causing sinkholes, erosion, or wall movement.
How Polyurethane Foam Seals Seawall Leaks
Our polyurethane foam injection process is designed to address these problems at their source.
- We drill small holes in the seawall or soil behind it.
- Polyurethane foam is injected into the voids and cracks.
- As the foam expands, it fills empty spaces, displaces water, and bonds with the surrounding material.
- The foam cures rapidly, forming a watertight seal and stabilizing the structure.
This process restores strength, stops active leaks, and prevents future soil erosion—all without the need for expensive seawall replacement.
Benefits of Using Polyurethane Foam for Seawall Repair
✅ Water-Resistant: The foam is hydrophobic and will not absorb or break down in water.
✅ Expands to Fill Voids: Foam reaches areas traditional methods can’t.
✅ Stabilizes Soil: Replaces washed-out soil and compacts loose ground.
✅ Non-Invasive: No heavy machinery, minimal disruption, and fast curing.
✅ Long-Lasting: Foam doesn’t degrade over time like some traditional sealants.
Whether your seawall is made of concrete, vinyl, or steel, polyurethane foam offers a permanent solution to leak and erosion problems.
