Basement & Radon Solutions, BRS Pros, lifted a section of the sidewalk for Cleveland. We lifted this concrete section by drilling holes in the affected areas of the concrete slab, in a regular pattern and spacing to allow for even pumping of concrete raising material underneath. Then with the holes in the slab, polyurethane foam is pumped in with the use of a high-pressure injection gun. The material instantaneously expands and fills the voids underneath the slab and in the soil, raising the concrete to it’s original level. This material also helps stabilize the soil underneath by filling in the gaps and compressing loose areas. Polyurethane typically cures in 15 minutes after injection allowing the areas to be fully available in minutes instead of days. After the polyurethane cured we filled in the holes to make it look back to normal. The poly foams we use are environmentally friendly, consisting of 39-49% renewable and recycled materials that are made in the USA. Our green polyurethane Biobased materials are not only good for the environment, but actually enhance the foam properties. It was a pleasure to help Cleveland’s home happy, healthy, and safe!
