Basement & Radon Solutions, BRS Pros filled a void in one section of the basement floor at the service door. We started out by drilling holes in strategic spots in the slab. The holes were drilled in the affected areas of the concrete slab, usually in a regular pattern and spacing to allow for even pumping of concrete raising material underneath. Then the polyurethane foam is pumped in the holes of the slab. The 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. This method is cost effective as well. Concrete raising is typically half the cost of replacing the same concrete. Ultimately, the cost of raising or stabilizing concrete is a direct reflection of how much leveling material the project will require. The poly also has a quick cure time, it will typically cure in 15 minutes after injection allowing areas to be fully available in minutes instead of days. The polyurethane foam is environmentally friendly, consisting of 39-49% renewable and recycled materials that are made in the USA. Our green polyurethane bio-based materials are not only good for the environment, but actually enhance the foam properties. It was a pleasure helping Scott make his home healthy, happy, and safe!
