What Causes Sinkholes in Largo
Pinellas County's covered-karst limestone dissolves gradually underground, and groundwater withdrawal can accelerate the process, which is why sinkholes continue to open across the county, Largo included.
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.
