There are wide range of substances and compounds that are mixed together with a liner for the cured-in-place pipe method or pipe relining. It’s a common occurrence for contractors who use pipe relining to choose epoxy as the primary mixture of the liner. There are people who wonder why they would use epoxy among the varied selection of resin materials in the market. This article will show you the importance of using epoxy in cured-in-place pipe lining.
The toughness and the longevity
The whole focus in the pipe relining method is to make sure that the resin liner will be properly fitted into the pipes and the resin material will be able to satisfactorily attach itself to the inner parts of the pipe. Of course the resin liner must be durable and will last for a long period of time so that the whole process will be worth all the work. It just so happens that epoxy is among the toughest resin materials out there while also a long-lasting compound.
It’s proven time and time again the epoxy is indeed a tough resin and should be used in pipe relining. Apart from improving and even boosting the durability of the old pipeline, it also protects the outer layer of the pipes from tree root attacks, which is a pretty common nuisance that affects many sewer pipes worldwide. Cracks, voids, and other damage to pipes rarely happens when epoxy resin is infused with it.
When it comes with longevity, epoxy resin liners can approximately last for a lifetime or 100 years. That kind of lifespan is very rare among commonly applied liners or even pipe materials that usually last only 50-75 years. If ever you relined your pipes with epoxy, you won’t have to worry about too much about restoring or even replacing your pipes for a very long period of time.
No issues with its chemical composition
Some resin liners out there are not commonly used unlike epoxy mainly because the substances that are found in them are organic compounds that can be harmful if improperly handled. Aside from that, there is also a concern with the odour. Most of the time, the organic compound that’s causing the smell is styrene. Styrene is very common among basic resin liners such as polyester and vinyl ester. Epoxy resins on the other hand don’t contain styrene or other organic compounds that produce odours.
Shrinkage is almost tenuous and is able to tightly attach itself to the pipeline
During the first years of the insertion of an epoxy liner, its bond with the pipe is still high, but it will eventually deteriorate and shrink. A few resin types can shrink fast as it grows older, affecting the quality of the entire pipe liner. What separates epoxy from its other resin family is that it doesn’t only attach to the pipeline tightly; its shrinkage is very low and inconsequential. Apart from that, the inner lining of the pipeline will also become sturdier if the epoxy resin can tightly bond with the old pipes.
