Below you will learn more details about this method and why trenchless sewer repair has become such an attractive choice for homeowners today.

Initial pipe inspection

Professional plumbers usually take the first step when fixing damaged or broken sewer lines by inspecting it with a small camera attached to a monitor. A hole must be made for this camera in order to access it; this can be accomplished either by opening up the sewer line before it leaves your home, or digging a small hole on your lawn. Data relayed by this camera may help identify whether the pipe has been compromised by trees roots, obstruction or damages that need repair.


Before relining, the inside of the pipe may need to be thoroughly cleaned or prepared in order to ensure a good seal with its new liner. If blocked by roots of trees, an innovative rotating blade system can be utilized to slice away at any roots that have formed and to slice off those that remain. This approach provides the easiest and most straightforward means of fixing sewer pipes if the source of roots has been eliminated.

Pipe lining

Most sewer issues can usually be repaired using pipe liners. A deflated fire hose-style liner coated with an exclusive epoxy is placed into the line before being inflated with air to push up against its inner pipe wall and push against any bladders that may exist inside of it to make space. Once hardened and cured, this bladder will be removed leaving you with a smooth solid surface ready for use in no time at all!

Final inspection

Once quality control has been established, a post-lining inspection video is conducted to confirm that the repair complies with stringent standards of quality assurance. Once this step has been accomplished, service can be restored for the owner and their newly relined pipeline will provide 50 more years of reliable service life.
