What is Sinkhole Repair?
Why St. Johns County needs Sinkhole Repair.
St. Johns County sits on a mix of sandy coastal soils, marine clay, and shallow limestone, with Atlantic hurricane saturation and a perpetually high water table working on it year-round. Differential settlement after named storms is the dominant failure mode here.
How we install Sinkhole Repair in St. Johns County.
Jacksonville foundations don’t fail gradually — they fail in clusters after every named storm. Most of our work in Duval and St. Johns is done in the 6–18 months following a hurricane season.
Our 4-step process — same protocol on every St. Johns County project.
- Free on-site inspection. Licensed specialist evaluates the structure, takes elevation readings, and identifies the root cause — at no cost.
- PE-stamped design. Our staff Professional Engineer specifies pier count, depth, torque, and capacity — sealed for permitting in your jurisdiction.
- Certified install. Partnered with Patriot Foundation Systems and Foundation Systems Supply crews drive each pier to a documented torque-to-capacity matching the design.
- Lift, load test, warranty. Hydraulic lift to target elevation, signed load test to confirm capacity, lifetime structural warranty issued same day.
