Lifting Sunken Concrete Slabs In Marmora, NJ

Persistent concrete settlement around the entryway sidewalk had become a major concern for a property owner in Marmora, NJ. Uneven slabs not only created an eyesore but also posed serious safety risks and liability issues due to potential tripping hazards. Fed up with the ongoing problem and seeking a permanent fix, the homeowner turned to Quality 1st for a reliable solution.

Our experienced team arrived promptly, assessed the site, and designed a targeted plan using our innovative PolyLevel Foam Injection system to lift and stabilize the sunken concrete.

By injecting high-density foam beneath the affected slabs, our crew was able to raise the sidewalk back to its proper level, creating a safe and even walking surface. To protect the newly stabilized area from future water infiltration and erosion, we applied our UV-resistant NexusPro Joint Sealant, which effectively seals cracks and joints while maintaining flexibility over time. The result was a fully restored, smooth, and visually appealing entryway.

With the repairs complete, the property owner no longer has to worry about safety hazards or further settlement, and can now enjoy a lasting, stress-free solution!
