Key takeaways

  • Every job starts with a camera inspection
  • The pipe must be cleaned before it is lined
  • The liner is cured with hot water, steam or UV light
  • Side connections are reopened and the result is recorded

Step 1: Inspect and plan

We run a camera through the pipe to see its material, length, bends, defects and connections. A locator marks the path above ground. From that we decide whether lining is the right method and choose the liner size and cure method.

We also plan access, flow and timing, because the line is out of service while the liner is installed and cured.

Step 2: Clean the pipe

A liner needs a clean surface. We cut roots, descale and jet the pipe until the camera shows clean walls. Grease, scale and debris left behind would leave voids and wrinkles under the liner.

In a fragile pipe we use gentler cleaning and stop early rather than risk damage.

Step 3: Install the liner

The liner tube is saturated with resin and moved into the pipe, either by inverting it with water or air pressure or by pulling it in. It is then inflated so it presses tightly against the old pipe wall, filling cracks and joints as it goes.

A cleanout, a manhole or a small access pit provides the entry point.

Step 4: Cure

The resin is hardened by circulating hot water or steam through the liner, or by pulling an ultraviolet light train through it. Temperatures or light speed are monitored through the cure.

Cure time depends on the length, diameter and method. When the liner is hard, the ends are cut and the inflation system is removed.

Step 5: Reopen and verify

Side connections are covered by the cured liner, so a robotic cutter reopens each one from inside the pipe. A final camera pass records the liner, the transitions at each end and every connection.

That video is yours to keep as a record of the finished repair.

Quick answers

How long does it take?

Many residential lines are done in a day. Longer or larger lines take longer, and we give you a window after the inspection.

Can I use water during the job?

No. The line is out of service during installation and cure. We tell you the window so you can plan.
