The Pipe Lining Process Explained

First, an initial inspection of the pipe is performed by means of a high definition, full-colour, and self-leveling sewer camera. During this process we will measure the linear footage and diameter of your pipes as well as locate and document any problems such as cracks, blockages, tree roots, etc. After the inspection, you are provided with a copy of the video, a not-to-scale drawing of your sewer’s layout, a deficiency report and a proposal to remedy any pipe problems we may have discovered.

Step 2. CLEANING

Second, the pipes are thoroughly cleaned utilizing hydro-jetting or mechanical methods. This process removes tree roots, blockages and scale buildup in preparation for lining. On occasion, sewer cleaning may be all that is required to remedy pipe problems such as slow drains and blockages.

Step 3. LINING

After the pipe is cleaned and excess debris is removed, the pipe can now be lined. The felt liner is measured and cut to the dimensions of the pipe such as length and diameter. Then the liner is saturated with a two-part epoxy and inserted into the pipe by the Pull-In-Place Method. An inflatable bladder is inflated inside of the epoxy-saturated liner causing the liner to take the shape of the pipe while it cures in place. After the epoxy has cured, the bladder is removed and a brand new pipe is left in place inside of the existing one.

Step 4. REINSTATEMENT

Finally, after the pipe has been lined, the branch lines that were covered over will have to be reinstated or reopened with our reinstatement equipment. Finally after the beaches have been reinstated, we perform a final camera inspection and a water flow test.
