Pipe Lining Saves D.C. A Washington D.C. contractor was contacted about a broken sewer pipe that ran underneath a river and a road. The D.C. contractor knew pipe lining was the best solution as this pipe was 10’ deep and the costs to dig and replace would be well over the cost of pipe lining. Pipe Lining was completed on 145-feet of 6-inch in less than one day! The Washington D.C. contractor also added in heat for rapid cure time. If you live in Washington D.C., Virginia or Maryland and want to know how pipe lining can save your property – call Perma-Liner!
