Concrete Lifting and Leveling Case Studies: Lifted walkways fixed with PolyLevel

Friday, November 7th, 2014 by Cassandra Santiago


A homeowner in Basking Ridge was experiencing concrete slab settlement. The walkways in front of and behind his home were lifting and separating. This was occurring due to the settlement of underlying soil, which then left spaces beneath the slabs, causing them to sink and erode. The uneven walkways were a potential tripping hazard for residents and visitors alike.


The Quality 1st Basement Systems team had the perfect remedy for slab settlement, PolyLevel. PolyLevel treatments involve injections of high-density polyurethane to raise sunken slabs back to their original positions. Several penny-sized holes are drilled into the affected concrete and then the injections are poured through. The polyurethane then expands for an accurate lift. This process is far less invasive than mudjacking, and it cures in record time! It takes about fifteen minutes and then the concrete is fully usable again. Plus, PolyLevel is made of recycled materials so it is environmentally friendly.

The Quality 1st Basement Systems crew was able to level the concrete walkways using PolyLevel injections. One of the best parts about PolyLevel is that the injection-site holes are virtually unnoticeable once filled. Now these walkways are looking smooth and even. The homeowner no longer has to worry about tripping hazards and he can fully enjoy these walkways!
