How Trenchless Sewer Line Replacement Work

The new trenchless sewer line repair is the revolution that has occurred in the replacement of sewer pipes. In the olden days, you had to dig through your yard just to repair a sewer line. This technology only requires a small hole—about the size of a sidewalk square—at both ends and then the plumber pulls a channel from your home to the main line. The best part is that the run doesn’t have to be on a straight line. Unlike other methods, the trenchless sewer line replacement can be done up to three 45-degree bends in a single pull. It is even possible to upsize a line from 4 inch to 6 inch so that your sewer can have a greater line capacity.

Sewer Repair and Replacement

How It Works

Just as the name suggests, this technology doesn’t need any form of digging. If there must be digging, then it’s only minimal. The procedure incorporates the Cured In Place Pipe lining technology (CIPP).

Step 1: Assessing the Sewer Line

The first thing done is to assess and clean the sewer line. This includes checking out the damaged pipes. The contractors will also measure the pipes to have everything cut to exact length. The CIPP liner is constructed of a hollow layer of polyester felt with an exterior polyurethane coating.

Step 2. Mixing Material

The mixture of 100% resin which acts as a catalyst is impregnated into the felt. This is referred to as wet-out. Not only does the felt act as a resin carrier, but also adds flexible strength to the sewer line.

Step 3: Transportation

Once the wet-out procedure has been complete, the lining will then be transported to the sewer line that needs replacement. It is normally transported in a refrigerated truck.

Step 4: Installation

The trenchless sewer line replacement work by positioning the lining within the sewer lines that need replacement by either of the two processes: winched into place or inversion (air or water). After everything is set in place, the liner is inflated by air pressure to push it against the wall of the pipe. A water can also be used in this case. Steam is then circulated within after this lining is inflated. This stage is crucial since it starts the thermosetting resin to harden or cure. After the hardening is complete, the lining is then cooled slowly to prevent shrinkage.

It is important to note that adding the above technology can be designed and manufactured in different ways depending on the project criteria of an individual.

The trenchless sewer line replacement is the most efficient and cost effective repair of modern times. The traditional method of replacing septic plumbing pipes involved a lot of labor, resources, time and machinery. However, the above explained technology doesn’t require any form of invasive excavation, extended time, excessive equipment and loads of labor. The continuous line after a trenchless sewer line replacement work makes the system more durable and sturdy against root invasion and other underground activities that may damage your sewer line.
