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 Key Largo
Classic collapse sinkholes are rare in the Keys, but Key Largo's porous coral-rock foundation soil shifts with tidal groundwater fluctuation, which can undermine a home's foundation the same way a sinkhole would.
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.
