When you use a quality drain relining service, it allows professionals to repair broken or damaged pipes without having to excavate them. This is why you will often see it referred to as ‘no dig’ or ‘trenchless’ options. The advantages are clear, this means that you do not have to worry about digging up buildings, pathways, driveways, or gardens to get to the pipe or sewer. However, few people know how the relining process works, which is why we will explain the process in detail.
First step – Preparing for relining
The first step is to make sure that the pipe itself is ready for relining. Oftentimes this means shooting a camera down there to ensure that there are no junctions, intrusions, or blockages. If there are any obstructions, these have to be removed beforehand. The pipe wall is cleaned to ensure a good bond.
Second step – Measure the length and apply
The second step is to measure the length of the pipe. After the relined pipe is cut to length, it is time to get the pipe liner ready for relining. This means mixing the hardening agent with the epoxy resin. This gets the pipe ready for use. A professional drain relining service will then pour the resin into the liner, and the liner is rolled repeatedly. This is going to ensure that the resin is impregnated into the material and evenly distributed along the entire length.
Third step – Blowing the liner into the pipe
After the second step of the Toronto drain relining process is complete, it is time to blow the liner into the pipe. The compressed air that is used here not only blows the liner into the pipe, but it will help invert the pipe at the same time. This is not unlike turning a t-shirt back to the way it needs to be after it was inside out. After this part is complete, the inside of the liner with the impregnated resin is now on the outside of the new pipe. It is stuck against the original pipe thanks to the compressed air.
Fourth step – Completing the process
After this is done, the Toronto drain relining process is almost complete. After it has been completed, it is important to wait a while. The resin is going to cure and form a hard protective coating. It is possible to speed up the process by using hot water or something similar or to let the relining cure by itself.
After this has been completed, it is important to check the pipe to ensure that there are no leaks. Once that has been completed, the new pipe is officially ready for use.
