Concrete Lifting and Leveling Before & After Photos

A homeowner contacted Quality 1st when they realized their concrete was sinking and settling. Not wanting to go through the expense and hassle of replacing the concrete, they were looking for an alternative solution.  Our System Design Specialist, Jay, inspected the area and suggested PolyLevel would be the best solution for the homeowner.

Our PolyLevel Foreman, Richard, went out to complete the installation. Richard and his team drilled penny- size holes into the concrete and  injected the polyurethane foam. They were able to lift and level the concrete within minutes without disrupting the surrounding areas. To complete the installation, our team installed NexusPro joint sealant to seal the joints of the concrete to prevent water from getting beneath the surface of the concrete and causing settlement in the future.

When this homeowner from East Windsor, NJ noticed a slight but dangerous lip forming along the edge of their backyard pool, they knew it was only a matter of time before someone tripped. Over the years, the concrete slab bordering the pool had sunk unevenly, creating a noticeable height difference where one section met the next. Instead of opting for a costly and invasive slab replacement, they chose a smarter solution: PolyLevel.

The Q1 team arrived and quickly assessed the situation. Using small injection holes, they pumped PolyLevel, a high-density polyurethane foam beneath the sunken concrete. Within minutes, the foam expanded, gently lifting the slab back into its original position. The repair was fast, clean, and didn’t require any heavy demolition. Not only did it eliminate the trip hazard, but it also restored the pool’s seamless look, all in a single afternoon.

Quality 1st Basement Systems lifted this sinking concrete in Somerset County with ease. The installation team injected PolyLevel underneath the slab. PolyLevel expands and lifts sinking slabs back into a level position, preventing trip hazards. This is a much better method than mudjacking, which is expensive and messy!

Quality 1st Basement Systems injected an expandable foam called PolyLevel underneath this sinking concrete slab. The foam filled the void underneath the concrete, pushing it back up and supporting it. Now this sidewalk in Somerset county is even and looks much better.

When concrete starts to sink, it’s often a sign of a bigger issue beneath the surface. This Dunellen, NJ property owner became increasingly frustrated with concrete settlement around their driveway, an issue that raised concerns about tripping hazards and diminishing curb appeal. After reaching out to Quality 1st Basement Systems, our team conducted a thorough inspection and quickly identified the root cause: voids beneath the concrete due to poor soil compaction and water erosion. With this information, we developed a targeted repair plan using our patented PolyLevel Foam Injection System.

This innovative solution involved injecting high-density polyurethane foam beneath the settled concrete. As the foam expanded, it filled the empty spaces and gently lifted the slabs back to their original, level position. The process was minimally invasive, quick to cure, and provided a long-lasting result. The homeowner was thrilled to see their driveway fully restored, both safer and more visually appealing, without the need for costly replacement. Another successful project completed with precision and care by the Quality 1st team.
