Marvin was looking for options in lifting and leveling his concrete driveway and sidewalks, and had heard about the injection technology, PolyLevel. PolyLevel has many more advantages over mudjacking, making it the only solution to lift sunken slabs. Small 5/8th inch holes are drilled into the concrete to inject the lightweight, polyurethane material. PolyLevel fills the voids and expands to lift and level the slabs and has a quick cure time to allow for access to the injected area within 15 minutes. The material is waterproof, preventing the PolyLevel from washing out, offering a more permanent solution than the slurry that is injected when mudjacking occurs. PolyLevel has left Marvin’s driveway and sidewalks level once again.
