How Does Trenchless Sewer Repair Work?

When you say the words “broken sewer line” to many homeowners, you’ll almost immediately cause them to wince or shudder. As far as plumbing problems go, this has long been one of the worst an average homeowner could find themselves dealing with. That’s because for many generations, a damaged sewer line could only be repaired by digging up your property, excavating the clogged-up line, and replacing it with a new one. The entire process took a long time and was extremely expensive. And that’s before considering the sheer amount of damage to your property that you’d have to replace after the initial repair was finished.

However, that doesn’t have to be the case anymore. While excavation isn’t necessarily a thing of the past just yet, there are processes which could repair a damaged sewer line while minimizing the invasive impact to your property, getting the job done faster, more reliably, and for cheaper than you may have thought possible. In this blog, we’ll take a look at how trenchless sewer line repair works so you can know what to expect and see if it’s right for fixing your problem.

Preparing Your Sewer Line

The first step to trenchless sewer repair is to run a visual inspection of your line through a camera inspection. This means feeding a plumbing camera through your line to spot any signs of damage and figure out if trenchless repair is a viable option. Once this inspection is complete, your plumber will then clean your sewer line to ensure that the walls are smooth and free from debris that could cause the trenchless repair not to work properly.

Once that’s complete, your plumbing crew then digs two holes—one on each end of the damaged sewer line that’s being repaired. Through these holes, they cut into the sewer line itself to access the damaged section. Once these holes are cut, they then send a specialized tool that’s connected to a winch through the damaged section of plumbing line.

Once this tool is in place, your plumber then cuts a section of cloth pipe lining and imbues it with a thick liquid resin. While the resin is still wet and the liner is still flexible, it is attached to the specialized tool and then pulled through the damaged section using the winch. Once the new liner is in place, it’s sealed on one end and the other end is attached to an air compressor. The compressor then inflates it, blowing it up like a balloon and making it fill the entire space inside your damaged pipe. Then, the new pipe liner is left to dry.

When the liner dries, it becomes solid and water-tight, but thin enough to only reduce the diameter of your pipe by just a small amount. After this point, the new liner is checked by camera one more time to ensure it’s properly set up and there are no bumps or wrinkles which may cause future clogs.

If everything checks out, then your new pipe is ready to go. Your plumber seals the holes they cut in your sewer line and then buries them again to restore your property back to normal. The entire process can take as little as two days (depending on weather and a few other factors.
