How we stop Failing Seawalls in South Florida
Failing Seawalls in South Florida: How We Can Help
In South Florida, seawalls are constantly tested by the natural forces of the ocean. The changing tides create repeated hydrostatic pressure on the wall, forcing water into the soils behind it. Over time, this water movement causes soil erosion, voids, and loss of structural support behind the wall — all without visible warning signs from the front.
At Floridian Concrete Lifting, we see this every week: properties with sunken soil, cracked walkways, and leaning seawalls. The culprit? Undermining from water intrusion.
The Solution: Deep Foam Injection
Unlike traditional repair methods that require excavation and heavy equipment, we use a non-invasive process called deep foam injection. This technique involves inserting rods behind the seawall to inject a two-part polyurethane foam below ground.
The foam expands upon contact, displacing water, filling voids, and binding loose soils into a solid, stable mass. The result is immediate — the soils are re-compacted, the wall is supported, and the surface is once again safe and level.
We use a proprietary hydrofoam blend engineered for marine environments. It’s waterproof, environmentally inert, and long-lasting — perfect for high-moisture coastal zones.
Why Seawalls Fail — And Why It Matters
Many property owners don’t realize that a seawall is more than just the visible concrete cap. Behind the wall lies the real issue: hydrostatic pressure from high and low tides slowly weakening the soils. When left untreated, it can lead to:
Sinkholes near the wall
Leaning or cracking seawalls
Erosion under patios or docks
Compromised foundations
If you live near the water and see soil settling or cracking, chances are your seawall is losing the support it needs.
