Broken Sewer Pipe Long Island. A Long Island homeowner contacted us regarding a broken sewer pipe on their property. The damage to the broken sewer pipe may have occurred by the earth settling, other underground utility construction, or roots penetrating the joints. Once there is a break in a sewer pipe, infiltration and exfiltration occur leading to tree roots entering the sewer pipe also. This particular Long Island homeowner had extensive landscaping and decided against the conventional dig and replace method. If you reside on Long Island and have questions regarding broken sewer pipes or Perma-Liner, please call us!
