This homeowner in Hollis, NH was concerned with the way the concrete stoop at his front door had settled 2 inches. This left a large gap between a brick step and the stoop. The concrete slab was also sloping towards the home itself, and so rain water was always flowing towards the wall of the house. Rather than tear out and replace the stoop, the homeowner reached out to our Erickson Foundation Solutions team to see if we could help.
Our team designed and proposed a solution utilizing PolyLevel, a polymer foam injection process similar to mudjacking. Our production specialists drilled tiny port holes in the surface of the stoop, and injected the expanding polymer foam into the voids beneath the concrete. They were able to lift the concrete up more than 1.5 inches, which corrected the pitch in the slab and allowed for rain water to now run away from the home instead of towards it. The process was quick and clean and involved no demolition or heavy machinery.
Concrete Settlement
The soil beneath the concrete slab was either not compacted well during installation, or had simply eroded away due to water penetration. The end result was it settled 2 inches.
Concrete Lifting
Our team lifted the slab more than 1.5 inches to help narrow the gap between the slab and the front step. It also lifted enough so that rain water will no longer flow towards the house.
Concrete Slab Settlement
The slab beneath the front step had settled 2 inches. This left the large gap you see here and also caused a slope in the concrete which allowed rain water to flow towards the house.
