Step OneStep One

Identifying the problemIdentifying the problem


The first step in our Pipe Rehabilitation process is to uncover the problem.

We uncover the problem with the use of an advanced, high resolution, fiber optic camera, specially designed for remote pipe investigation.

The camera is sent through an existing access point in your piping system such as a clean out. (or when necessary through the removal of a toilet.)

The camera can inspect the entire length of the pipe, unveiling any problematic areas.

Pipe Preparation (Cleaning)Pipe Preparation (Cleaning)

Our proprietary cleaning tools, that are only made available to our Pipe Rehabilitation network of companies, maneuver to the problem areas the same way that the camera was able to remotely inspect your piping system.

These cleaning tools will remove any blockages and get your pipe back to its original diameter. We can remove tree root intrusions, de-scale cast iron, and eliminate calcite build up.

This unique cleaning process is a necessary step for preparing the pipe, for rehabilitation.

Pipe Rehabilitation (Lining)Pipe Rehabilitation (Lining)

The liner is comprised of four components.

i)Needlepoint Felt Tube (laminated on the outside)ii)Plastic Tubeiii)Rubber Tubeiv)Vinyl Strap


The four components are assembled at the manufacturing plant in Canada, and shipped in large rolls to the Pipe Rehabilitation network of companies throughout North America.

The manufacturer undergoes quarterly audits, in order to maintain all the approvals necessary to comply with the universal plumbing code (UPC).

Once the length of liner required is calculated from the camera investigation, the amount of liner is cut off the large roll onsite.

Special plugs are fastened to each end of the liner. This will allow for the rubber to inflate like aballoon once positioned inside the pipe.



A predetermined amount of a twopart exothermic, catalytic, epoxyresin, is mixed together.

When the two parts are mixed, a chemical reaction occurs, causing them to harden.

Note that the technicians are not wearing masks while mixing theepoxy. They do not require masks as the type of epoxy resin used does not off gas, or have any odours.

The mixed epoxy resin is then poured into the inside of the liner in between the laminated felt tube and the plastic and rubber tubing.




The epoxy resin is rolled throughfrom one end of the liner to the other with metal rollers.

The epoxy resin is tinted to ensure complete saturation into the felt.

Note the small bottom right picture illustrating compete saturation.




The epoxy saturated liner is then folded in half and secured with low tack adhesive tape.

This ensures that the liner will easily fit through the existing access, through to the area of pipe to be rehabilitated.




The liner is then either pushed or pulled through the old pipe from the access point, and then positioned in the exact place required.




The liner, while positioned in the pipe being rehabilitated, is then inflated with an air for a period of 3-8 hours.

During that timeframe theepoxy resin hardens, creating a stronger and more flexible pipe formation than a brand new ABS or PVC plastic pipe.

Brand new piping of course would have required excavation to be installed.




Once the epoxy hardeningprocess has taken place, the rubber tube is deflated and pulled out.

The felt tube and epoxy resin has become the new pipe insidethe old pipe.

Lastly, a final camera investigation is performed to confirm that thereare no defects.
