What To Expect When You Have Your Sewer Repaired With A Liner

If you're constantly battling tree roots in your sewer line, you may put up with it because you dread the thought of digging up your yard to replace the damaged pipe. However, you should keep in mind that the roots cause more damage each time they invade the pipe, and it's probably a matter of time until the pipe crumbles and collapses. Then, you won't have any other option but to dig it up and replace it. As long as the pipe is still structurally sound, you can have repairs done that are less costly and less disruptive than digging up your yard. You can have a new sewer liner put inside instead. This is how it's done.

Start With A Video Inspection

The first step is for the contractor to examine the inside of the pipe with a video camera. As the camera is fed through the pipe, a video is displayed in real time on a monitor. The video shows the condition of the pipe as well as whether it is straight or if it has bends. All this information helps the contractor determine if putting in a new liner is a possible option for your situation.

Cleaning The Pipe Is Next

The inside of the sewer pipe must be clean before a liner is pulled through. The pipe may have built-up scale and sludge on it. There may be tree roots and dirt filling the space. All the roots and debris can be easily removed with a high-pressure water jet or sewer snake that cuts up the roots. Once the inside of the pipe is as clean as possible, it is ready for the liner to be installed.

The New Liner Is Prepped

Before pulling the liner through the pipe, the contractor has to prep it first. This involves cutting the liner to the right length and then pouring resin into it. The liner itself is a flexible material. The resin is added so the liner becomes hard like a pipe when the resin dries. The resin is mixed on the spot and poured inside of the liner until the liner is saturated with it.

Sewer Repairs Are Done

The final step is to pull the saturated liner through the pipe. This might require digging a small hole in your yard if there isn't a manhole that can be used. The liner is pulled through in such a way that it turns inside out. This puts the wet side with the resin against the inside of the sewer pipe. The liner is then inflated so the sides of the liner press against the sides of the pipe. The inflation balloon is kept in place to hold the liner open until the resin cures. Once it has cured, it forms a hard plastic pipe that is situated inside the sewer pipe. Roots won't be able to get through, and if they destroy the old pipe eventually, it won't matter because a new pipe will already be in place.

Having a liner installed is one of the easier and less disruptive ways to solve a sewer pipe problem. You essentially get a new sewer line without having to tear out the old one, so that saves your yard from being torn up by trenches and heavy machinery. Not only that, it is also a less expensive option, especially when you factor in what it costs to replace sod and landscaping damaged by digging up your yard.
