Signs of a Sinkhole
- Cracks in your driveway, walkways, or exterior walls
- A depression or low spot forming in your yard
- Doors and windows that suddenly stick or won't close right
- Sloping, sagging, or uneven floors
- Water pooling in a spot where it never used to
- An exposed or sunken area along your foundation
What Causes Sinkholes in Sanibel
Classic limestone sinkholes are not a documented risk on Sanibel itself, but barrier-island soil settling and storm-driven erosion can still undermine a home's foundation, and we diagnose and repair that the same way we would a sinkhole.
How We Fix Sinkholes
Depending on what our evaluation finds, we use compaction grouting — pumping a cement-and-grout mixture deep into the soil to fill voids and stabilize the ground — or void filling, which lifts and supports affected concrete with structural polyurethane foam. Both methods are done with a real diagnosis first, not guesswork.
