PolyLevel Concrete Lifting & Leveling Services in Trenton

Is your sidewalk or driveway sinking and uneven? How about your patio or front porch steps? Uneven concrete not only looks bad, but it can also be a dangerous tripping hazard. Concrete leveling is faster, less disruptive and more cost-effective than tearing out and replacing the concrete.

Thrasher Foundation Repair uses a process called PolyLevel to permanently lift and stabilize sinking concrete slabs with a high-density polyurethane formula. PolyLevel concrete repair offers many advantages:

  • Lightweight - Won't add weight to existing soil
  • Waterproof - Won't wash out
  • High-capacity - Lifts heavy loads
  • Minimal disruption to your slab and property
  • Environmentally friendly
  • Great for leveling sidewalks, driveways, pool decks

If you have a slab foundation or concrete outside your home that you need re-leveled, Thrasher Foundation Repair is your expert contractor. Call today to schedule your free, no-obligation inspection and estimate!

New homeowner Eric C. bought an older home and was looking to add an addition on to the home. Before starting the project, he kept on smelling a musty odor anytime it would rain. Worried that his crawl space was getting wet, he decided to give Thrasher a call.

System Design Specialist John Hollingsworth went out to Eric’s home and found a solution to keeping the crawl space dry. The crew installed full perimeter waterproofing with WaterGuard and also put in a Triple Safe Sump Pump. Eric was extremely pleased to know that the crawl space would remain dry and that he could continue on with the addition.
