This process is also referred to as “Pipe Bursting”. This process replaces a sewer line by digging two access points, using your old sewer line as a guide to burst a new one piece sewer line thru this process creates a long lasting sewer which is very resistant to root intrusion. With less seams, shifting of lines or cracks is almost non-existent. William Frankel Plumbing offers a 20 year warranty against root intrusion on new sewer lines.
Sewer lining is a process of using a mix of fiberglass resin and epoxy to seal cracks and holes in sewer pipes to create a new seamless sewer line. Pipe lining can be done on clay, cast iron and concrete pipes, as well as some others. Lining is best suited for applications where other methods of replacement are not available.
