Before & After Photos

Disheveled concrete around a backyard pool had become a growing concern for a Princeton, NJ homeowner, creating safety risks for family and guests and diminishing the overall appearance of their outdoor space. The homeowner reached out to Quality 1st after noticing the slabs were continuing to sink and crack, unsure of how to address the problem without a full replacement. After a detailed inspection, our System Design Specialist discovered that soil erosion and empty voids beneath the concrete were causing the slabs to shift and settle over time.

To correct the issue, the crew used our patented PolyLevel Foam Injection repair method, a fast, non-invasive approach designed to lift and stabilize sunken concrete with precision. Small holes were drilled into the affected slabs, and high-density foam was injected underneath, expanding to fill gaps and raise the concrete back to its original level. The process was completed with minimal disruption, and the results were immediate.

The homeowner was left with a safe, smooth, and fully restored pool deck that not only looked better but was also built to last for many more seasons of outdoor enjoyment!

This Mays Landing, NJ homeowner noticed their concrete porch steps had sunk two inches, so they contacted Quality 1st Basement Systems for a solution. Our System Design Specialist, Joe Mancini, suggested the best repair method for the homeowner would be the Polylevel Injection. Unlike mudjacking, polylevel is stronger, environmentally friendly, waterproof, and has a fast recovery time.

Don't let sinking concrete get you down! A homeowner in Mays Landing, NJ noticed their walkway to the front door was sinking and settling. They contacted Quality 1st Basement Systems to learn more about raising the concrete versus replacing the entire concrete area. We sent Concrete Repair Specialist, Joe, out to perform a full inspection and provide a solution! Using PolyLevel our team was able to to bring the concrete to a raised position and permanently stabilize the entire walkway, removing the trip hazard. 

This Rocky Hill, NJ pool needed to be fixed before next summer, so the homeowner called Quality 1st Basement Systems into inject PolyLEVEL underneath the sinking concrete. The slabs were raised and now this pool patio is level and looking great!

This sidewalk in Bridgewater, NJ had three slabs that were sinking and settling about 3 inches into the ground. Quality 1st Basement injected PolyLevel underneath the slab and lifted it back into place. PolyLevel sets in just 15 minutes and is a cheaper option than replacing concrete.
