Quality 1st Basement Systems was contacted by this homeowner in Pennsville, New Jersey due to their concrete walkway sinking and settling. We sent our System Design Specialist, Chris Bowe to inspect the concrete. He suggested we use polyurethane foam to lift and level the slab. Our foreman Ramon arrived at the home and used our PolyLevel Injections. PolyLevel has expanding properties that allow the concrete to become raised. Within 20 minutes, the job was complete! The homeowner was satisfied with the results and they didn't have to worry about tripping hazards anymore!
