Trenchless sewer repair is a way to fix or replace a damaged sewer line without digging a long trench across the yard. The work is done through one or two small access holes, which can save landscaping, driveways, and walkways.
Common Trenchless Methods
- Pipe lining: a flexible liner coated with resin is pulled into the old pipe and hardened in place, creating a new pipe inside the old one.
- Pipe bursting: a tool pulls a new pipe through the old one while breaking the old pipe apart into the surrounding soil.
- Spot repairs: a short liner patches one damaged section.
When It May Be a Good Fit
Trenchless repair can work well when the pipe has cracks, root intrusion, or leaking joints, and when digging would disturb a driveway, patio, trees, or a finished lawn. It can also reduce the time the sewer is out of service, which matters when the home has only one line.
When It May Not Work
Not every pipe can be lined or burst. A pipe that has fully collapsed, has severe sags, or has sharp bends may need traditional digging. Some sections near the house or under the basement floor can also be hard to reach. Lining makes the pipe slightly narrower inside, which matters in some cases.
How the Decision Is Made
A camera inspection comes first. It shows the pipe material, the type of damage, and whether the line is a good candidate. The line is usually cleaned before any lining work so the liner bonds well. Permits may also be required.
Ask about the expected life of the repair and any warranty before work starts.
If your sewer line keeps backing up, a camera check to see what repair fits is the place to begin. For questions about digging versus trenchless options, you can go over the choices with a plumber at (833) 603-1840.
