PolyLevel Concrete Lifting & Leveling Services in Shell Knob

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.

  • 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

Anytime James would pull his car into the garage of his home in Shell Knob, MO there would be a big dip that he would have to drive over each time. He was worried that the settlement would get worse and affect other parts of the driveway. He started researching driveway repair options and came across Thrasher. After reading some great customer reviews, he decided to give us a call to learn more about our approach.

The Thrasher crew went out to James’s home. During the inspection, the slab in front of the driveway had dropped 3.5 inches. We explained to James the benefits of our 3-part concrete protection system and got to work. We leveled the concrete with PolyLevel, then closed the joints with NexusPro Joint Sealant and then applied SealantPro to protect the whole driveway.
