We received a phone call from Marabella high rise condos in the Westwood Wilsher area of Los Angeles in regards to a problem they were having with their old cast iron pipes. With our trenchless sewer repair process we were able to save the 4” and 6” cast iron roof drains and downspouts. These old cast iron lines ran through a major structural footing, the stairs and directly under huge trees. Our trenchless sewer repair process is able to fix old cast iron roof drains and downspouts in Los Angeles properties causing minimal damage. On this particular Los Angeles project we used our Perma Lateral air inversion system. The Perma-Lateral system is used frequently to repair old cast iron pipes in Los Angeles because of the multiple benefits. If you have any questions in regards to old cast iron roof drains, broken sewer lines or Perma-Liner’s Perma-Lateral system, and you live in California, call us anytime. We are available 24 hours to answer any of your questions regarding old cast iron roof drains, broken sewer lines and the Perma-Lateral system.
