Concrete Lifting and Leveling Before & After Photos

After years of exposure to moisture, a Fair Lawn, NJ homeowner began noticing uneven concrete and sinking slabs around their backyard pool deck, a clear sign of settlement. Concerned about both safety and appearance, they reached out to the concrete experts at Quality 1st for help.

Our team conducted a thorough inspection to identify the underlying causes of the issue, pinpointing which areas required correction. To restore the deck’s stability, we utilized our PolyLevel Foam Injection System, a high-performance solution designed to lift and level sunken concrete. The lightweight polyurethane foam was injected beneath the affected slabs, where it expanded to fill voids, stabilize the soil, and raise the surface back to its original elevation with precision and control.

Once the lifting process was complete, our crew finished the project with a full application of NexusPro Joint Sealant to seal cracks and joints throughout the deck. This UV-resistant, flexible sealant prevents future water intrusion, protecting the concrete from further damage while maintaining a clean, polished appearance.

With both advanced systems working together, the pool deck was fully restored to a safe, stable, and attractive condition, allowing the homeowner to relax and enjoy their backyard with complete confidence!

This concrete sidewalk near this Farmingdale, NJ patio had sunken a couple of inches due to washout of the soil underneath the slabs. The PolyLEVEL concrete leveling system was injected under the concrete to raise the concrete back to its original position. The concrete raising was completed in just a few hours and was usable to these homeowners within thirty minutes!

These homeowners from Farmingdale, NJ had concrete in their back pool deck as well as the walkway leading to the front door, that had about 2 inches of sinkage. Quality 1st Basements lifted and leveled their sunken slabs with our PolyLevel solution. PolyLevel is a lightweight but strong foam that is injected underneath slabs of and expands until the slab is level. 

A Farmingdale, NJ homeowner was interested in repairing the sinking concrete around their large, inground pool.

Concrete replacement not only has a long demo process but also has a long curing process. PolyLevel is quick to install, causes no disruption to the surrounding area and within just 15 minutes of completion the entire area is safe to use. 

Quality 1st Basement Systems used PolyLevel to fix this settling basement floor in Ridgewood.

The process is minimally intrusive, with penny-sized holes drilled and filled, and quick, taking only 15 minutes to cure.
