Repairing pipes has never been easy, affordable, and convenient all thanks to trenchless repair technology. There is a wide assortment of methods under this new age pipe repair system, and one of the most used and effective repair techniques is Cured-in–Place pipe or CIPP for short. In this article we’re going to take a look on what are the steps contractor take in order to perfectly execute CIPP.

1. Survey the pipes with the use of a camera

People often mistaken that the CIPP liner is immediately introduced to the host sewer pipe which is completely false. In reality, there are a lot of processes that must first be conducted before integrating the liner. The very first thing contractors do is to check out the sewer line for any problems like collapsing pipes, plant roots, blockage, etc. It’s important to ensure that the issues mentioned must not be present during the process since it will cause the liner installation to be defective or become a complete failure.

2. Removing any obstruction in the sewer line

The obstructions found must be removed at all cost, which is why contractors carry equipment that can help eliminate the said blockades. If there are tree roots present in the pipeline, a rodding or drilling machine is used to cut it out. A hydro jet is always used to clear out the clogs in the sewer pipe. In cases where the pipes are too oxidised, then a cast pipe is required in order to guarantee the success of the procedure. Once the sewer line is free from any blockade and any other issues, the pipeline of the sewer system is then measured including its height and length. Accuracy is an important part of this procedure.

3. Epoxy resin liner mixture

Fiberglass is a great material for pipe relining, but epoxy resin is widely used by plumbing companies so in this article we will focus more on epoxy material. The resin is fused with the liner to create a sturdy pipe lining. Once the liner and epoxy resin have been properly mixed, it is placed into a launcher that will help insert the newly formed epoxy liner into the sewer.

4. Inversion

The liner is inserted into the pipeline through the use of air or water inversion. It will depend on what the contractor prefers, but it doesn’t really matter since both of these inversion techniques will definitely get the job done.

5. Curing

Curing is the process in which the resin liner is hardened so that it will be able to properly adhere itself to the host sewer pipe. This step can be accelerated with the use hot water, steam, or even UV rays.

6. Final examination

Before the pipe relining contractors pack their things and return to their office, they will first conduct one final examination of the work site. They do some inspections of the cured pipe liner if there are any flaws with the process and to guarantee the property owner that the CIPP process was a complete success.
