Pipe Lining in Chicago. A Chicago business was about to have their sewer pipe line dug up and replaced with a new cast iron pipe. Luckily the Chicago business owner did some research online and found pipe lining as an appropriate solution to the conventional dig and replace method of the past. The current sewer pipe was missing a piece almost the entire length of the pipe, thus allowing roots to penetrate the sewer pipe. The Perma-Lateral air inversion system was used in this particular pipe lining installation to rehabilitate the sewer pipe at least another 50+ years.
