Before & After Photos

A homeowner in Hillsdale, New Jersey had sinking and settling slabs on their sidewalk. The homeowners contacted Quality 1st for a solution.

PolyLevel was injected into the concrete through small penny-size holes. The foam starts to expand and begin working within 30 minutes, lifting the concrete back to its original position. 

When not properly sealed, concrete walkways can sink and crack when water gets beneath the slabs and erodes the soil. This customer called on Quality 1st Basements to help fix a problem that was bound to get worse. PolyLevel injections lifted the slabs and the NexusPro joint sealant will help divert surface water away from the joints to prevent future washout. 

This homeowner in Hillsdale, NJ was noticing cracking on the slabs leading to their front door. They called the professionals at Quality 1st Basements for a free inspection and quote. Our System Design Specialist suggested Polylevel to lift and level any sunken slabs that were creating unsafe tripping hazards. The job was finished with NexusPro Sealant to keep the cracks sealed so it would be protected from any moisture and debris that would cause it to erode. The homeowner was satisfied with their results and felt like their home was safer for them and their family. 

A Jersey City, NJ homeowner knew it was time to repair their sinking concrete porch, so they contacted Quality 1st Basement Systems for a solution. As a solution, we used the Polylevel Injection to lift and level the concrete. Since the installation, the homeowner had not experienced any other concrete issues around your home. 

Quality 1st Basement Systems repaired this sinking pool deck in Ocean Gate, NJ, by using the Polylevel Injection. Polylevel is waterproof and recovers within fifteen minutes. Our crew carefully drilled small, penny-like homes into the uneven concrete. They then injected the polyurethane foam into the empty void. The foam then expands and lifts the slab to its desired height. The homeowner was happy with the results!
