Our sewer repair crew recently performed a drain cleaning and Perma Liner installation in Somerset, NJ for Lester Entin Associates. The job took about 5 days because of the length of the sewer line being 600 feet of cast iron. The technicians descaled and cleaned out the 600 feet that ran from the front of the building to the street.
The crew also had to hydro jet after descaling to remove the rust and debris from the line before installing the Perma Liner inside the sewer line. As you can see from the photos there were 2 spots inside that had to be excavated in the concrete floor. They also poured new concrete into those 2 spots after the job was complete. The 300 feet long Perma Liner was installed with a 4-inch liner and there was one elbow, as seen in these photos.
