What Causes Sinkholes in St. Petersburg

Pinellas County's covered-karst limestone dissolves gradually below the surface, and when the soil above finally gives way, it can open suddenly — the pattern behind the sinkhole activity documented across the county, St. Petersburg 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.
