What Causes Sinkholes in Marco
Sinkholes in the Marco Island area tend to develop as gradual subsidence over months rather than sudden collapse, but the underlying process is the same limestone dissolution, and we diagnose and repair both the same way.
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.
