Basement & Radon Solutions, BRS Pros, lifted John’s generator pad by using our poly lift. First we drilled holes in strategic spots on the slab – holes are drilled in the affected areas of the concrete slabs, usually in a regular pattern and spacing to allow for even pumping of the poly foam underneath. Then the polyurethane foam was pumped in the holes in John’s slab. Polyurethane foam was pumped in with the use of our high-pressure injection gun. The poly foam instantaneously expanded and filled the voids underneath the slab and in the soil, raising the concrete to it’s original level. The poly foam also helps stabilize the soil underneath by filling in the gaps and compressing loose areas. 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 helping John make his home happy, healthy, and safe!
