Before & After Photos

A homeowner from Browns Mills, NJ noticed that the concrete step leading to their front door had settled over time, creating an uneven and potentially hazardous entryway. Wanting a solution that was both quick and long-lasting, they chose to repair it using PolyLevel and NexusPro.

With PolyLevel, experts were able to lift the sunken step by injecting a lightweight, expanding foam beneath the concrete, raising it back to its proper height with precision. To finish the job, they applied NexusPro sealant to fill any cracks and joints, protecting the area from water intrusion and future settling. The result was a stable, level step that restored safe access to the front door and improved the home's overall curb appeal.

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.

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.
