PolyLevel Concrete Lifting & Leveling Services in Sioux

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

Job Stories From Sioux County, IA
WaterGuard and Sump Pump Keep Basement Dry in Orange City, IA

A homeowner in Orange City, IA was planning on adding more living space and bedrooms in the basement for his family. But before he could add a bedroom, there was problems with water coming into the basement and he didn’t want the space to flood. Ready to learn about possible waterproofing solutions, he gave Thrasher a call.

Our crew was able to determine that the current sump pump couldn’t keep up and the water was coming in through the walls. We installed a new sump pump and put in WaterGaurd, so then the water would be directed into the sump pump. The walls were also encapsulated with CleanSpace to keep the area dry.

Basement Waterproofing in Granville, IA

These homeowners in Granville, IA wanted to be able to use their basement as a space for storage, living, and as a play area for their grandchildren. However, due to a surplus of moisture, it was a musty and damp area they felt wasn’t a healthy enough environment. The homeowners trusted our reputation and gave us a call to waterproof their basement.

Thrasher arrived at the home in Granville, IA and began by undergoing a full inspection of the wet basement. The homeowners chose to have our teams install a combination of our waterproofing products. To begin, we installed our WaterGuard interior drainage system and CleanSpace waterproof barrier around the full perimeter of the basement. To drain the collected water outside, we installed two of our TripleSafe sump pump systems to guarantee the basement stays dry year-round. The customers were thrilled with our waterproofing solutions, and they couldn’t have been more excited to have their basement as a functional space once again.
