Before & After Photos

Check out this sidewalk we raised in Hightstown, NJ. We drilled small penny-size holes into the concrete slab and injected PolyLevel underneath to raise the concrete back to level. 

PolyLevel is a waterproof, environmentally friendly, lightweight polyurethane foam that permanently stabilizes the sidewalk. 

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. 

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.
