Before & After Photos

With help from both our System Design Specialist, Jay and PolyLevel Foreman, Iian, Quality 1st Basements was able to provide a permanent solution to the sinking patio area in Old Tappan, NJ. The homeowner had contacted Quality 1st when they got tired of the puddles forming in the middle of their patio from the settlement. They wanted to avoid replacing the patio area at all cost. 

Iian was able to lift all for sinking slabs back to level, removing the dip in the patio. Now with the patio leveled, water would no longer get trapped in the middle and simply flow towards the grass. 

What began as a slight dip in the sidewalk soon became a daily safety concern for a homeowner in Westwood, NJ. The entryway concrete had gradually sunk and shifted, creating uneven surfaces and trip hazards for anyone approaching the front door. Concerned about both safety and curb appeal, the homeowner reached out to Quality 1st for a permanent solution.

Upon inspection, our team discovered that the concrete settlement was caused by unstable soil conditions, specifically erosion and poor compaction beneath the slab.

To correct the issue, we implemented a tailored repair plan using our innovative PolyLevel Foam Injection System. This lightweight, expanding foam was injected beneath the sunken sidewalk to fill voids and raise the concrete back to a level position with precision. Once lifted, we sealed all joints and cracks with our NexusPro Joint Sealant, which prevents water infiltration and future soil washout.

This dynamic approach not only restored the sidewalk’s safety and appearance but also provided long-term protection, giving the homeowner complete confidence in their newly stabilized entryway.

The slabs around a Teaneck, NJ swimming pool were sinking into the ground. Quality 1st Basement Systems raised them back up into place by injecting PolyLevel under the concrete. Now the pool is safer and ready for summer fun!

Check out how our Concrete Repair Team raised this sinking and settling front walk way back towards its original position! This homeowner in Teaneck, NJ, was constantly worried about the small trip hazards that had formed due to the concrete movement that occurred over time. Noticing that the trip hazards became move noticeable was a major sign that movement of the slabs was still occurring. We used our PolyLevel Injections to bring the concrete walk way back to a raised and level position.  

After noticing a growing trip hazard along the sidewalk near their home, a homeowner from Teaneck, NJ decided to take action. The concrete slabs had sunk unevenly over time, creating an unsightly and potentially dangerous walkway. Rather than tearing out and replacing the sidewalk, they opted for a quicker, more cost-effective solution. 

Using PolyLevel, a high-density polyurethane foam, contractors were able to lift and level the sunken concrete precisely and efficiently. Once the slabs were stabilized, NexusPro ,  a durable, UV-resistant sealant, was applied to the joints and cracks, preventing water infiltration and future erosion. The result? A smooth, even sidewalk that looks great, improves curb appeal, and enhances safety for years to come.
