Trenchless Sewer Pipe and Why It’s Useful

Why is trenchless sewer pipe repairing so useful? The simple answer is that it causes less damage to your property. Regardless of where the sewer line runs in your property, to replace it, this old school method involves using heavy equipment to dig a trench down to the broken or damaged pipe.

Obviously that means that the beautiful deck that took you months to complete is gone. That nice tree you like seeing when you drink your coffee in the morning? Gone.

The good news is that this article is about how having a sewer problem doesn’t mean you have to excavate all around your home.


The difference between the trenchless and the traditional method is that there is no need to excavate and make a mess. When we get to the job site, we will do a visual inspection of the inside of the pipe. This familiarizes us with the specifics related to your sewer line replacement. We will take measurements and get the liner ready.

Cured-In-Place Pipe

The trenchless method begins by inserting a sewer liner to renew the pipe from the inside out. This liner is a soft tube-like material that is inserted into your existing pipe. This is known as a Cured-in-Place Pipe (CIPP).

CIPP works by filling the felt liner with a liquid epoxy resin. Once we place the line to cover the entire damaged pipe, we inflate the liner so the epoxy oozes out of the liner and coat the walls of the damaged pipe, taking its shape. After a few hours, the liquid hardens and becomes your new sewer pipe.

How We Save Time in Repairing Sewer Pipes

The easiest way to install the liner is by running it from the upstream access point, such as from a hole dug near where your sewer joins the municipal system or from a manhole. The liner is sent downstream from there to where the damaged pipe enters the home or building where it is being repaired. After the resin cures, it creates a jointless, corrosion proof, tight-fitting replacement pipe within a pipe. Following inspections using cameras to confirm the CIPP has completely cured and rectified the problem, connections are made at both ends and the repair is complete.


Trenchless repairs save you time, money and the hassle of an excavation team in your home for weeks. However, there are more benefits to the performance of your new sewer system.

  • The new pipe is stronger than PVC
  • It is guaranteed to last at least 50 years
  • You get a brand new pipe, instead of a repaired pipe.
  • Any blockages or fractures are left behind. You are essentially rebooting your sewer system.
