PolyLevel is a lightweight, strong high-density polyurethane foam, developed by our sister company Supportworks and only available to an exclusive network of foundation and concrete repair contractors. A more recent technology than mudjacking, PolyLevel utilizes polyurethane foam rather than a mud-cement-slurry mixture to lift and level uneven concrete driveways. Mudjacking requires a messy, disruptive installation process and larger port size than PolyLevel polyurethane foam. Additionally, mudjacking doesn’t address the underlying issue (stability) as well as PolyLevel does. Concrete driveways sink and crack due to the soil below expanding, contracting, washing out and leaving voids into which heavy concrete slabs sink. Mudjacking material is heavy, adding more weight on top of the already unstable soil, and is susceptible to the same issues of wash out and void creation. PolyLevel is waterproof, so it won’t wash away or degrade over time. During installation, the expanding foam not only raises concrete driveway slabs, but also compacts the soil around it, adding stability to help prevent future sinking and settling.
