Concrete Lifting and Leveling Before & After Photos

This homeowner from East Windsor, NJ had front steps that were starting to separate and the water slipping through the cracks was making it worse. They called Quality 1st Basements for help.  They used Polylevel to restore the stair back into place, no longer creating a tripping hazard for the homeowner and their family. 

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.
