Concrete Lifting and Leveling Before & After Photos

When concrete starts to sink, it’s often a sign of a bigger issue beneath the surface. This Dunellen, NJ property owner became increasingly frustrated with concrete settlement around their driveway, an issue that raised concerns about tripping hazards and diminishing curb appeal. After reaching out to Quality 1st Basement Systems, our team conducted a thorough inspection and quickly identified the root cause: voids beneath the concrete due to poor soil compaction and water erosion. With this information, we developed a targeted repair plan using our patented PolyLevel Foam Injection System.

This innovative solution involved injecting high-density polyurethane foam beneath the settled concrete. As the foam expanded, it filled the empty spaces and gently lifted the slabs back to their original, level position. The process was minimally invasive, quick to cure, and provided a long-lasting result. The homeowner was thrilled to see their driveway fully restored, both safer and more visually appealing, without the need for costly replacement. Another successful project completed with precision and care by the Quality 1st team.

In Gillette, NJ, a homeowner’s dream of a relaxing poolside escape was disrupted by an increasingly uneven and unsafe concrete deck. What started as subtle settling soon turned into visible slab shifts and trip hazards, posing a danger to anyone walking around the pool. Concerned about safety and structural integrity, the homeowner reached out to Quality 1st Basement Systems for a permanent solution. Upon inspection, our team discovered that soil erosion and poor compaction beneath the concrete were causing voids, leading to the uneven surface and instability.

To address the issue, we installed our innovative PolyLevel Foam Injection System, which involves injecting a high-density, expanding polyurethane foam beneath the sunken slabs. This foam expands to fill voids and gently lifts the concrete back to its original level with precision and minimal disruption. This powerful repair technique not only restored the pool deck’s appearance but also ensured long-term stability and safety, leaving the homeowner with a smooth, secure, and worry-free outdoor space.

An uneven sidewalk is not only an eyesore, but it can be extremely dangerous to pedestrians. To remove the trip hazards created by the sinking and settling concrete, our concrete repair team injected PolyLevel beneath the slab. PolyLevel is a polyurethane foam that is extremely strong and durable. When it hardens beneath the concrete, it is able to stabilize the slab and withstand the weight for years. PolyLevel does not break down, it is waterproof and environmentally friendly. The sidewalk is now permanently stabilized and safe for pedestrians again!

A resident in Hanover, New Jersey noticed their concrete sidewalk was settling. Looking for a solution, they contacted Quality 1st Basement Systems for an inspection to opinions for a permeant solution.  Our System Design Specialist, Jeff Pitek, explained that the soil underneath was the main problem causing the concrete slab to settle. He recommended our PolyLevel Concrete Raising Solution. PolyLevel is a waterproof foam that fills the voids and raises the slabs back towards their original position. 

Our foreman installed the PolyLevel Injection System which is done by drilling small penny- size holes into the concrete and injecting the foam into the voids underneath. PolyLevel is environmentally friendly and light weight, which will not add weight to the existing soil.

A Cedar Knolls, NJ, homeowner wanted to repair their sinking concrete patio, so they contacted Quality 1st Basement Systems for an estimate. We used the Polylevel Injection to lift, level and stabilize the entire concrete area. Leveling the patio removed all the minor trip hazards, allowing the furniture to be uneven in the ack. The joint was sealed to ensure no water erosion underneath the soil.
