Before & After Photos

This homeowner in Columbus, New Jersey saw their concrete walkway was sinking and becoming unlevel. They contacted Quality 1st Basement Systems and our system design specialist suggested they use polyurethane foam to raise the concrete. Our foreman used our PolyLevel Injection method by injecting the polyurethane foam into the slab to fill the voids underneath. This process is repeated until the concrete is lifted and leveled. When the job was complete, the homeowner was pleased with the results and they didn't have to worry about tripping hazards anymore! 

Roxbury Township had been experiencing sinking sidewalks which became hazardous to the community. They wanted a solution without the headache of removing and replacing the concrete so the Township called Quality 1st! PolyLevel was injected into the concrete slabs, raising them back up to the desired level, creating a safe walk way.

A homeowner in Sussex, NJ noticed their concrete walkway was sinking and becoming unlevel. They contacted us for a solution, and we used our PolyLevel Injections to bring the concrete to a raised and level position. Check out the transformation! 

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 homeowner from Jobstown, NJ noticed their porch concrete was sinking. They called Quality 1st Basements for a free estimate. One of our System Design Specialists recommended PolyLevel to lift the concrete.

PolyLevel foam was injected under the slab and expands to lift the concrete slab back into place. Although the foam is light it's very strong and the homeowner could walk on their concrete the same day. The process is a simpler and faster solution to concrete replacement.

The homeowner could now enjoy their lifted and leveled porch.
