Concrete Lifting and Leveling Before & After Photos

Injection of PolyLevel foam beneath a sinking sidewalk slab helps to fill the voids beneath  and lift the slab. Foreman Nick Boldman and his crew completed this installation for this customer to eliminate the trip hazard.

Don't let tripping hazards affect your peace of mind. Quality 1st Basement Systems can provide a solution for concrete sinking in any area around your home. This homeowner in Collegeville, PA contacted us to repair their settled walkway area. We used our PolyLevel Injections to bring the concrete back to its original position. PolyLevel is waterproof and environmentally friendly making it the perfect solution to fill voids and stabilize any sinking concrete area. 

Quality 1st Basement Systems repaired this sinking concrete in Trappe, PA by using PolyLevel Injections. We got to the source of the problem which is the soil underneath the concrete slab. Over time, soil becomes to wet, too dry or overall is poorly compacted and cannot support the weight of a heavy slab. When this occurs, the slab begins to sink. PolyLevel is an environmentally friendly, waterproof, polyurethane foam that fills the voids between the slab and soil and lifts it back towards its original position. 

A Collegeville, PA homeowner found their concrete steps were settling, thus creating a gap between the steps and porch of the home. Luckily, Quality 1st Basement System arrived with the best repair solution. We used the Polylevel Injection to repair the concrete. Our crew injected a waterproof polyurethane foam underneath the concrete to fill the void. Once the void was filled, the foam expanded and lifted the concrete back to its original height. Fifteen minutes after the installation, the foam fully cured and the concrete was repaired. The homeowner was very pleased with the final results!

This driveway was uneven, and had large cracks throughout the surface, as you can see in the "before" photo. Our team swooped in to use our PolyLevel injection system. PolyLevel injected beneath the sunken slab raises it to its original level. Additionally, the cracks were sealed to seamlessly blend the concrete once more!
