A homeowner in Allentown, PA noticed their concrete sidewalk was sinking and becoming unlevel. They knew this could become a dangerous tripping hazard, so they contacted us for a solution. We knew that our PolyLevel Injections would be able to lift and level this uneven concrete. PolyLevel is a lightweight polyurethane foam that is injected underneath the slabs to raise it. When the job was complete, the homeowner was able to walk safely on the sidewalk, restoring their peace of mind!
