Some repairs get a little more technical, particularly where a main line meets a lateral connection.
At our recent church project, the team installed a specialised junction liner, sometimes called a satellite liner, to repair a tee connection without excavation.
The liner is positioned right at the junction, then inverted into the lateral. A specialised bladder holds it firmly against the walls of both pipes while the resin cures. It’s precise work, and the positioning has to be right.
For this job, that meant we could repair the structural damage at the branch connection without opening up more of the site than necessary. On a property like this, with access, existing structures and the surrounding grounds to work around, that matters.
There’s a fair bit that happens before the liner goes in too, including camera work and careful preparation. Once it’s cured though, the junction is sealed and the repair is done below ground, where it should be.
