The Trenchless Sewer Repair Process

Signs of Sewer Damage

Sewer line problems can make themselves known through a variety of nasty symptoms.

Suspiciously lush spots on your lawn, sewage backups in certain areas of your home, and cracks in your foundation are but a handful of ways these problems can manifest.

The underlying causes can range from burst pipes and leaks, to tree root disruption and blockages. Without professional sewer inspection, it’s all guesswork.

Sewer Line Inspection

Mainstream’s sewer repair team is trained to analyze your sewer line, determine its overall condition, and locate problems that are affecting your home’s plumbing.

Camera inspection allows us to travel through your sewer line and take a closer look. Our team can then draw conclusions about the nature of your sewer line problem, where it is located, and how to proceed with repair which can include either traditional sewer line repair or trenchless.

Trenchless Sewer Repair: The Plan Of Action

Cured-In-Place Pipe Repair

If we are able to detect your sewer problem before major damage occurs, trenchless sewer line repair could be the way forward!

A classic example is cured-in-place pipe (CIPP) sewer repair. This is a trenchless restoration method which involves inserting a seamless, jointless, and root-resistant lining inside an existing sewer line.

The lining, which contains resin, is exposed to a curing element which allows it to adhere to the inner walls of your sewer line. Voila! Once fully cured, you have a brand new pipeline.

It is worth noting that CIPP is EPA Certified and has no negative impact on the environment.

Pipe Bursting Trenchless Sewer Line Replacement

If, however, our analysis renders CIPP sewer repair impossible, there’s no need to despair. We have other non-invasive procedures at our disposal. Pipe bursting is a great alternative if portions of your sewer line have collapsed or are otherwise unable to accept a new lining.

This trenchless sewer replacement method is as satisfying and simple as its name suggests. Two holes are dug at both ends of the line. A steel expander head is then dragged through the existing pipe. Its slightly larger diameter allows it to shatter the old pipe and push its pieces into the soil as it’s traveling. A new replacement pipe follows closely behind and takes the spot of the old. The new sewer line is then simply reconnected at both ends and is ready for use.

Our state of the art equipment can pull pipe through the ground at a maximum working force of 60,000 psi.

The Future Is Trenchless

Our home is 66 years young and it was time to replace the original water lines and sewer lines. I was amazed that they were able to streamline, fix old plumbing mistakes and make our entire water system user friendly. Thank you Cody, Donovan and the third guy that I can't remember his name. They were all professional, polite and knowledgeable.
