Concrete Lifting and Leveling Before & After Photos

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.

This concrete patio area in the backyard of this South Brunswick Township, NJ home had settled near the foundation and on the out edge of the patio. System Design Specialist, Jay A, recommended PolyLevel as the perfect solution since it would allow us to raise the existing concrete, avoiding replacement all together. PolyLevel, is a light weight, environmentally friendly foam that lifts the settling concrete back to level. 

An uneven sidewalk is not only an eyesore, but it can be extremely dangerous to pedestrians. To remove the trip hazards created by the sinking and settling concrete, our concrete repair team injected PolyLevel beneath the slab. PolyLevel is a polyurethane foam that is extremely strong and durable. When it hardens beneath the concrete, it is able to stabilize the slab and withstand the weight for years. PolyLevel does not break down, it is waterproof and environmentally friendly. The sidewalk is now permanently stabilized and safe for pedestrians again!
