Trenchless Sewer Line Repair Explained

Trenchless sewer line repair is a newer, faster, and less invasive form of sewer repair. Instead of using excavation equipment to dig giant holes in your yard or home, this method utilizes the failed or deteriorated pipe as a host to repair the line from the inside.


Trenchless Pipe Relining

If you need a relining, the technician will first send a camera into the sewer to find what is wrong with your sewer line. If it's determined that the pipe just needs to be relined, then the plumber will begin the process with a sewer cleaning service to ensure that the liner adheres properly.

Once the line is clean, a resin-imbued pipe liner is placed inside the existing drainage pipes. The liner is inflated so that it fills the entirety of the plumbing line. The liner then cures over the next 1-2 days forming the new structural line, basically creating a new pipe within the old pipe.

The technicians will come back after the liner has hardened and tested it to ensure the pipe has been properly fixed and is leak-free.

Trenchless Pipe Bursting

If it is discovered that your pipe is too badly damaged for a relining, then the technicians will use the pipe bursting method. This process utilizes a winch to pull a bursting head through your sewer line, which actively tears the line apart while still in the ground.

Attached to the back of the bursting head is a new sewer pipeline that is made from a flexible plastic material. After the head has torn up all of the line, the new pipes are fastened to your drains and main sewer connection.


  1. Quicker Repair

Traditional methods require large holes to be dug and eventually fixed, which takes a substantial amount of time. Trenchless repairs only need two small holes, which are much quicker to make and fill back up.

  1. Cost-Effective

Because the trenchless process doesn't require any structural modification, excavators, or much digging, you will save money on upfront and clean-up costs. This is also a more straightforward process, so not only will less labor be needed it will also require fewer hours to complete the job.

  1. Less Digging

Trenchless technology only requires two small holes, which is much less than traditional means. This minimizes how much harm is done to your yard and the surrounding area.
