It’s a flexible tube that is coated with resin which is pulled or blown into the damage or inflate pipe. The resin then creates a pipe within a pipe which is corrosion resistant and jointless by its hardening. Lining reduces the diameter of the lateral pipe that connects a home to the main sewer line. The diameter reduces by a quarter of an inch; this does not affect waste removal from your house.

Unlike pipe lining, pipe bursting can be done on a collapse lateral sewer line; if there is room that can allow a cable to be drag through the old pipe. Pipe bursting is pulling a new pipe through a damage pipe. This simultaneously fractures the old pipe outwards. Pipe bursting requires one to dig access holes on both sides of the lateral pipe.

According to experts pipe lining and bursting are equally durable, the cost for trenchless sewer line replacement vary due to:  soil type, material prices and how deep underground sewer is.
