Sewer line needs replacement in home with no basement. Line is directly under supporting wall in center of house. All contractors in my area say it's unsafe to dig up without under pinning. Found an under pinning company and is going to cost$30,000 to fix due to location of sewer line. From front entrance to stairs to second level floor will be dug up including flooring and concrete slab the house sits on. Terrible location for a sewer line. A major flaw in design/engineering
