Pipe Lining in D.C.. A Virginia contractor was asked to travel to a restaurant in the Washington D.C. area to take a look at two damaged drain pipes that needed pipe lining. After cleaning and televising the pipes, the contractor scheduled the work to be done that evening after closing time. The impregnated liner was blown through the old, damaged pipes and air pressure was maintained for three hours. Pipe lining is a cost-effective method to rehabilitate old, weak pipes. Pipe lining will also save your property from the damage of digging and replacing.
