RaiseRite Concrete Lifting offers two different methods to raise settled concrete. This video illustrates the polyurethane concrete lifting option. This method involves fewer and smaller holes than traditional mudjacking. Perfect for this application the holes were hidden within the faux grout lines of the stamped patio. Polyurethane fills the voids, and expands to raise the concrete. After seconds, the material expands into a foam that will never lose density. Raising settled concrete, is the cost- effective solution when compared to replacing good concrete. RaiseRite is proud to be the only company in Wisconsin to offer both mudjacking and polyurethane concrete raising. Do it Right…with RaiseRite
