Lifting a Settling Driveway Concrete Slab in West Omaha

The T. family residence was built in 1985 with the original 18-foot wide driveway slab still in place. Over time, the area of the driveway nearest the garage had settled 5 inches down and towards the garage. This slab settlement created trip hazards when walking in and out of the garage, and made it awkward when the homeowner entered or exited the garage with her vehicle. In addition, the slope of the driveway slab was directing water toward the home rather than away from it, promoting further slab settlement and potentially future basement water problems and foundation damage.
Thrasher Basement Systems proposed a polyurethane injection system, PolyLEVEL, to provide an economical, quick and effective solution for lifting the homeowner’s driveway slab. PolyLEVEL is a two-part urethane that when combined expands into a rigid foam used to fill voids, stabilize slabs and lift concrete. Once injected through small, penny-sized drilled “ports” in a slab, a chemical process converts the urethane product into a strong, rapidly-setting foam material.
Prior to the PolyLevel application, the sunken slab was almost 5 inches lower than the garage floor.
Minutes after the PolyLevel application, the slab was back on its original level.
This is a picture of the driveway before, with the slab visibly sinking, most prominently on the right side.
PolyLevel cures in minutes. Just a few moments after the application, the slab was back to level and ready to be used.
