RaiseRite Concrete Lifting offers two different methods to raise settled concrete. This video illustrates the mudjacking process. A void caused by traffic vibrations is being filled to raise a bridge approach on a section of highway in Fond du Lac County. Raising settled concrete is the cost-effective solution, when compared to replacing good concrete. With minimal lane disruption, concrete raising can complete a project in much less time then replacement. RaiseRite is proud to be the only company in Wisconsin to offer both mudjacking and polyurethane concrete raising.
