The homeowners of this Fleetwood, NC residence were aware of the liability and trip hazard their sinking slab had become over the years. With a two-inch difference in height of the slab, they needed to have this problem corrected without major disruption to their yard and landscaping.
Tar Heel Basement Systems used the PolyRenewal method to stabilize and raise the sinking slab. A small (penny-sized) hole was drilled below the slab and a two-part polyurethane foam was injected. The void causing the settlement was filled and the slab was raised, creating safe and even sidewalk!
