This homeowner in Whitestone, New York noticed their driveway was sinking and causing them to trip and injure themselves. A driveway should provide safety, not dangerous tripping hazards! They called Quality 1st Basement Systems and we repaired the issue with our PolyLevel Injections. PolyLevel is a polyurethane foam that is injected directly underneath the slab. PolyLevel has expanding properties that allow the concrete to be brought to a raised position. When the job was complete, the homeowner was happy to see their driveway was raised and level.
