Trenchless Technology: Defined and Explained

Trenched Sewer Line Replacement

The conventional method for dealing with the repair or replacement of sewer lines requires that your yard, sidewalk, driveway, or parking lot had to be torn up in order to access the pipe. This can require equipment as simple as a shovel or as complicated as a backhoe, trencher, or other heavy equipment. Use of this equipment on a lawn can be destructive by itself, let alone the work that goes into fixing it once dug up.

Conventional methods of sewer line replacement may require that walkways and driveways, landscaped areas of your yard, or the parking lot of your business be removed and then replaced once the job is finished.

This adds to the expense of repair or replacement and needs to be considered when comparing the cost of conventional sewer line work over trenchless technology. Less invasive, trenchless sewer repair can eliminate much of this work when you find the need to replace a sewer pipe.

What is Trenchless Technology?

Plumbers have increasingly added trenchless technology to their services. There are several methods of trenchless sewer line replacement and a professional can determine which is right for your situation. The beauty of trenchless technology is that only one or two holes need to be made on your property in order to repair or replace a faulty sewer line. Using equipment, specifically designed to do the job, plumbers are able to replace and repair sewer lines, without the mess of conventional methods. This is how they do it:

CIPP (cured in place pipe) – For this method of trenchless technology, a special liner is filled with resin then pulled or blown into the pipe. Once the liner is in place, the resin hardens and provides a smooth seamless pipe that will allow it to flow freely. The life cycle of CIPP is 50 years, so once replaced you will not need to worry about your sewer line for a long time to come.

Pipe Bursting – This method of trenchless technology requires two holes and can be used for repair or replacement of short or long sections of sewer pipe. A cable is inserted into the pipe, and attached to a bursting head. It is then pulled through the existing sewer line, pushing away the old pipe while it inserts a new pipe in its place.

The biggest difference in these methods of trenchless pipe replacement is that CIPP reduces the diameter of your pipe. For most applications, this will not be a problem because CIPP is seamless, offering a smoother interior surface than the pipe it replaces. With pipe bursting trenchless technology, the diameter of the pipe being replaced can easily be increased. This can offer a greater flow of your pipes and is especially beneficial for businesses, municipalities and large homes in Sacramento.
