Concrete Lifting and Leveling Before & After Photos

A front step of a walkway in Mercer County, NJ had settled about 2 inches. Fixing it was fast and easy with the PolyLevel solution! The polymer foam was injected under the settled slab and expanded until the slab was level with the surrounding slabs. Now the homeowner has an even surface to walk on. 

This homeowner in Robbinsville, New Jersey noticed their concrete stairs were becoming unlevel. This happens because concrete is poured over backfilled soil. Over time, this soil settles and creates voids under the concrete. Our System Design Specialist, Alvin Reed, suggested they use PolyLevel Injections, which was installed by our foreman, Ramon Romero. Within 20 minutes the concrete was safe to walk on!

This home in Robbinsville, NJ had a sinking sidewalk, so the homeowner contacted Quality 1st Basement Systems. Our System Design Specialist, Alvin R., inspected the sidewalk and measured how far the concrete had sunk. Since the concrete sunk 3/4 of an inch, Alvin recommended the Polylevel Injection as the best concrete repair method. Polylevel is a durable and long-lasting method for concrete repair. It's waterproof, environmentally friendly, and takes fifteen minutes to recover. After the poly level installation was complete, the sidewalk was repaired. The homeowner was happy with the results!
