This homeowner in River Edge, New Jersey noticed their concrete sidewalk was sinking and becoming unlevel. The homeowner contacted Quality 1st Basement Systems and our System Design Specialist, Joseph DelVecchio suggested they use polyurethane foam to lift and level the concrete. Our foreman used our PolyLevel Injections to inject the foam into the voids underneath. This will allow the concrete sidewalk to become raised and level. When the job was complete, the homeowner was happy with the results!
