A homeowner in Norristown, PA noticed their concrete sidewalk was sinking and becoming unlevel. They knew if this went without repair, it could cause tripping hazards for pedestrians. They knew to call us for a solution, so we sent our System Design Specialist to provide an inspection. Our specialist suggested using polyurethane foam to lift and level the concrete slabs. Our foreman used our PolyLevel Injections to bring the concrete back to its original position. Check out the difference!
