Trenchless sewer line replacement is a relatively new procedure that is growing in popularity in Trenton. It is becoming more popular largely because it is less invasive and less time consuming – and therefore less expensive – than traditional methods of replacing a sewer line.
But what goes into the trenchless replacement process? There are four main components.
Component 1: Camera Inspection
Before starting the process of replacing the sewer line, your contracting crew will first use a special flexible camera to inspect the line. This allows them to determine just how much of the sewer line needs to be replaced, so they know where to drill the holes (Component #2) and how much pipe will be needed.
Component 2: Guide Holes
Once they have a visual on what they are doing, the crew will drill a small hole in the ground at either end of the section of the line that is to be replaced. These holes – much narrower than traditional trenches – go through the ground and into the surface of the pipe below.
Component 3: Specialized Cable
Through the holes, a special cable is run from one end of the damaged line, through the pipe to the other end. One end of the cable has a special bursting head attached to it, while the other end is attached to a device that will pull it through the line. This cable will act as the guide for the new pipe.
Component 4: Durable & Flexible Piping
Attached to the bursting head, following right behind the cable, will be a length of flexible but durable piping, usually high density polyethylene (HDPE). When the cable is pulled through the old line, the bursting head breaks open the old pipe from the inside, and the new pipe gets dragged in behind to replace it.
That is about all there is to it. Just like that, your Trenton home’s busted sewer line is replaced with a new, durable piece of material that will last for many years. To learn more, give Resolve Rooter a call today!
