Trenchless Sewer Line Repair Techniques

Trenchless sewer line repair is becoming more and more popular as the go-to method for sewer line repair in Longmont and nearby areas. Not only do plumbers prefer this method, but it provides a long list of benefits to the customer – less invasive, cheaper, shorter turnaround times, among others. When looking for a contractor to repair your sewer line, you’ll see a lot of terms that can be confusing if you don’t know what they mean. We’ll explain the various trenchless sewer line repair techniques here.

1. Pipe Lining

Pipe lining or relining is one of the most common trenchless sewer line repair in Longmont. It works by first digging two holes, one at the entrance and one at the exit of the pipe to be relined. A sleeve or liner is inserted into the existing pipe and then coated with a liquid epoxy and filled up with high pressure steam, causing the liner to expand to fit the shape of the existing pipe. As the epoxy dries, it forms a pipe within a pipe, sealing any existing cracks.

Trenchless pipe bursting in Longmont CO2. Pipe Bursting

The second most popular trenchless sewer line repair technique is pipe bursting. This is usually called for when your existing pipe is just too far damaged – by tree roots, bellies, or collapsed piping – to repair via pipe lining. A bursting head is pulled through the old sewer line, breaking up the pipe as it goes along and dragging behind it the brand new replacement pipe.

3. Directional Boring

This method is not nearly as talked about as the first two. Directional boring is also called horizontal directional drilling (HDD), and it requires the use of heavy duty equipment and a directional boring unit. Directional boring is ideal for sensitive areas or beneath roadways where asphalt cannot be torn up. First, a pilot hole is dug where the new pipe will lie. Then, a reamer enlarges the hole to the diameter of the pipe, while also dragging behind it the brand new pipeline.

4. Thumping

Thumping (aka non-directional boring) is another method great for under sidewalks or roadways. Again, two holes or pits are dug at the entrance and exit of the pipe. However, instead of dragging the new pipe behind a drill or bursting head, the hole is made first and then the new pipe is drug backwards through it. If you’re investing in trenchless sewer line repair for your home, you really only need to worry about pipe lining and pipe bursting since they are the most common methods of sewer replacement. As long as you’re aware of the benefits that trenchless sewer repair in Loveland has to offer, and you choose a licensed and insured plumber for the job, you’ll be in good hands.

  1. I have been curious as to how water lines are being repaired without trenching. I was under the impression that it is necessary to dig a trench to get utilities to a certain area. This article, however, educates me of the different techniques used such as directional boring/drilling to get utilities installed from one point to another, without the asphalt being destroyed. I think this is a beneficial method as it is less invasive and has a shorter turnaround time just like what you mentioned in this article. I think I’ll consider this in the future should I need installation of utility pipelines. Thanks!
