What Causes Sinkholes in Jacksonville
Sinkholes are less common in Jacksonville than in Central Florida, but the same soluble limestone still underlies the area, and when settling does happen — often from drainage or soil conditions near the St. Johns River — we diagnose and fix it 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.
