This Sewell, NJ homeowner was experiencing sinking slabs around their pool area. Since they were getting ready to close their pool in a few short weeks, they decided to wait before replacing the slabs. A few days later they noticed one of Quality 1st Basement Systems Concrete Lifting & Leveling trucks in their neighborhood and decided to call for a free estimate. 

System Design Specialist, Jeff Pitek, went out to meet with the homeowners and inspect the slab area. Jeff recommended PolyLevel for it would lift and level the slabs. The homeowner's biggest concern was that if they replaced the sinking slabs, the concrete would no longer match the old. Since PolyLevel simply raises the existing slab, they knew this was the exact solution they were looking for! 

The Sewell, NJ homeowners were thrilled that they were able to close their pool just hours after the installation was complete.

A customer in Washington Township, NJ contacted Quality 1st Basements for a solution to their sinking concrete driveway. Quality 1st used  Polyurethane foam known as PolyLevel to fill the void below each of  the slabs, raising them back to level. Polylevel is a state- of- the- art approach to repairing sinking concrete. Rather then injecting mud or cement under the slab, we inject high- density, lightweight, structural- grade polymers to lift, level and stabilize. Once the driveway was raised, the team sealed the joints with NexusPro joint sealant to prevent cracking and crumbling in the future.

This driveway in Sewell, NJ was sinking and settling, so the homeowner contacted Quality 1st Basement Systems. Our System Design Specialist, Chris B., inspected the driveway and measured the height of the sunken concrete. Within a few days, our crew arrived at the home and repaired the driveway using the Polylevel Injection Method. Using specially designed equipment, our crew injected the polyurethane foam into the voids underneath the slab. Once the void has been filled, the polyurethane foam expands and lifts the concrete slab to the desired height. After the repair, the concrete looked as good as new!

Job Stories From Sewell, NJ
Concrete Patio Lifted in Sewell, NJ

A homeowner in Sewell, New Jersey saw their concrete patio was sinking and becoming unlevel. This happens because concrete is often poured over poorly compacted soil. Over time, this soil settles and creates voids underneath, which causes the slab to shift. This can be dangerous because a friend or family member could trip and injure themselves.

The homeowner contacted Quality 1st Basement Systems and our System Design Specialist, Chris Bowe, was able to provide an inspection of the home and help them find a solution. Upon his inspection, Chris noticed that the concrete patio was shifting and unlevel. He suggested a polyurethane foam to lift and level the slab.

Our foreman arrived on the site and began the process of using the PolyLevel Injection System. This process is done by drilling small, penny-sized holes into the slab and injecting the polyurethane foam into the voids underneath. This process can be done within a day and does not require the use of heavy equipment. 

PolyLevel is a lightweight, environmentally friendly, and water-proof solution that will not wash out, or will not add any weight to the existing soil. The polyurethane has expanding properties that allow for an accurate lift and leveling of the slab.

When the job was complete, the homeowner was pleased with the outcome. They were able to safely walk on their concrete patio without the concern of tripping or injuries.
