A North Whales, PA homeowner was ready to address their concrete patio and walkway since both areas had settled causing trip hazards. They decided to have Quality 1st Basement Systems out to inspect both areas and see if PolyLevel would be the perfect solution. Polylevel is a polyurethane foam that fills the voids between the soil and concrete slab. Over time, soil becomes weak if too wet or too dry causing movement. The settlement occurs and then trip hazards form! Our team used PolyLevel to lift, level and stabilize both areas to ensure no future settlement occurs.
