Sewer Repair Memorial Area. A main sewer line needed repair in the Memorial Area of Houston. The main sewer line had been badly penetrated by roots; luckily the roots had only affected one 6-foot section of the main sewer line. Perma-Liner was contacted for a Sectional Point Repair solution. Instead of relining the entire main sewer line from manhole to manhole, Sectional Point Repairs are used as spot repairs. If you live or work in the Memorial Area of Houston and need sewer repair solutions, call Perma-Liner today!
