Poly slab jacking uses hard, dense, expanding polyurethane to quickly and cost effectively raise settled or unstable concrete. It permanently fills voids without replacing concrete!

How it Works:
Two polyurethane liquid components are mixed and injected (aka polyurethane injection) under pressure below the area to be lifted. The liquids react, causing it to expand and harden. The effect is similar to the aerosol can foam used to seal around windows. Our polyurethane foam stays a liquid for a few seconds before expanding to aid in disbursement around the injection site. Once the reaction takes place, it hardens and expands very quickly which creates a stronger force under the surface to be lifted.
