PolyJacking & Concrete
Lifting in St. Louis
Sunken, uneven concrete is more than an eyesore — it’s a safety hazard. Our advanced polyurethane foam injection lifts and levels concrete in hours, not days.
What is PolyJacking
PolyJacking (also known as foam jacking or poly leveling) is a modern concrete lifting method that uses high-density polyurethane foam injected beneath sunken slabs to raise them back to their original position. It’s faster, lighter, and more durable than traditional mudjacking.
Lightweight
Polyurethane foam weighs just 2-4 lbs per cubic foot compared to 100+ lbs for mudjacking material, reducing future settling.
Fast Cure Time
Foam sets in approximately 15 minutes, so you can walk and drive on the repaired surface the same day.
Waterproof
Unlike mudjacking grout, polyurethane foam won't wash away or absorb moisture, providing a permanent solution.
Long-Lasting Stability
Polyurethane foam expands to fill voids and stabilize the soil beneath, preventing future sinking and providing a durable, long-term repair solution.
