Eliminating Concrete Settlement In Marmora, NJ

Friday, June 20th, 2025 by Rebecca Brossa

Challenge

Concrete settlement had become a constant source of stress for a property owner in Marmora, NJ. The once-smooth entryway sidewalk had shifted and sunk over time, creating uneven surfaces that posed serious tripping hazards. With growing concerns about safety and potential liability, the homeowner knew it was time to stop the cycle of temporary fixes and invest in a permanent, professional solution. That’s when they contacted Quality 1st for expert help.

Solution

Our experienced team arrived on-site and conducted a detailed assessment of the damaged area. We determined that the best approach would be to use our advanced PolyLevel Foam Injections, a minimally invasive method designed to lift sunken concrete by filling voids beneath the slabs. As the high-density foam expanded, it raised and stabilized the sidewalk, restoring it to its original level without the need for demolition or replacement. To further protect the repair and extend the life of the concrete, we applied our UV-resistant NexusPro Joint Sealant. This durable, flexible material seals joints and cracks to prevent water infiltration, one of the leading causes of future settlement. With both PolyLevel and NexusPro in place, the entryway was transformed into a smooth, safe, and visually appealing walkway. The homeowner was thrilled with the results and now enjoys peace of mind knowing their property is both protected and more inviting!

Moisture intrusion and shifting soil beneath the surface caused the concrete sidewalk to settle unevenly, leading to sinking slabs and a hazardous walking surface.

Our crew drilled small, precise holes into the sunken sidewalk and injected PolyLevel foam beneath the slabs, where it expanded to fill voids and gently lifted the concrete back to a safe, level position.

To protect the repaired sidewalk from future damage, we applied NexusPro Joint Sealant along the cracks and joints, creating a flexible, waterproof barrier that prevents moisture intrusion and erosion.
