Concrete Lifting and Leveling Before & After Photos

What began as a slight dip in the floor soon turned into a serious concern for this Cherry Hill, NJ homeowner. Their indoor patio had become noticeably uneven, a clear sign of concrete settlement likely caused by shifting soil and moisture intrusion beneath the slab. Over time, the instability worsened, posing not just a cosmetic issue, but a potential safety hazard within the home. Concerned about long-term damage, the homeowner contacted Quality 1st Basement Systems for a professional solution. Our team arrived promptly to perform a comprehensive inspection and determined that the most effective approach would be our patented PolyLevel Foam Injection System.

This advanced repair method involves injecting high-density polyurethane foam beneath the sunken sections of concrete. As the foam expands, it fills voids in the soil, lifts the slab back to its original position, and provides long-term stabilization, all with minimal disruption and no need for demolition. Within hours, the indoor patio was level, safe, and structurally sound once again. The homeowner was impressed not only by the efficiency of the process but also by the long-lasting results.

Thanks to PolyLevel, they regained both the functionality and aesthetic appeal of their indoor space, along with peace of mind knowing their home is protected against future settlement!
