The concrete slab in this carport had sank more than 4 inches over the years. Rain water had slowly washed out the soil below the slab, causing it to drop. The most severe slab settlement was this back portion that overlooked the back yard.
Tar Heel Basement Systems was able to lift the sinking slab nearly 4 inches using their innovative PolyRenewal system. PolyRenewal is a structural foam that expands beneath the slab, compresses the soil below and lifts the concrete. The homeowner was able to pull their car into the carport when they returned from work this day.
