3 Reasons why Epoxy Resin is Frequently Used in CIPP Lateral Lining Pipe Repair

In the cured-in-place-pipe method, an epoxy resin liner is placed into the pipes and allowed to mix and coat the inner pipeline. After the resin is given enough time to be cured/hardened, it will become part of the main sewer line. The resin is not just for aesthetic purposes as it helps in increasing the durability of the pipes and allows wastewater to smoothly flow through the sewer line without any problems. Among the dozens of resin types that are used for pipe repair, epoxy resin is commonly used in CIPP lateral lining. Find out the reasons why this particular resin is frequently used in pipe relining.

 

  1. Low shrinkage which enables to embed itself tighter to the host pipe

In the process of pipe relining, it’s integral that the resin that is attached and cured in the pipe lining will be able to stick and properly bind with the old pipes. Failure to do so will jeopardise the entire sewer main line after decades of usage. With such matters that need to be addressed, it’s a relief for contractors and clients that epoxy resin is one of the few liners in the market today that will be able to properly bond with its host pipe and still become functional for many years. Another thing is that all resins will eventually shrink due to many years of use and constant exposure to water waste. However, with epoxy resin you won’t have to worry too much about its degradation as it’s a resin type has a very low shrink rate ―— and because of its low shrinkage, epoxy is able to attach to the pipeline easily.

 

  1. Free from harmful compounds

In the past and even today, there were some issues with some types of resin liners that contain harsh chemicals, volatile organic compounds (VOC’s), and even carcinogens as it’s harmful. There are still resin liners that have VOCs and need proper handling to be applied well and avoid chemical hazards. Most resins that contain VOC’s also produce odours that are clearly chemical-based. Fortunately, epoxy resin isn’t made of any form of VOCs and other noxious substances which makes it completely safe. The resin also doesn’t produce chemical odours which make it better for anyone living near the work site.

 

  1. Durable and very long-lasting

Despite being just embedded into the pipeline, epoxy resin can actually compete and is even considered to be better than most pipe materials in the market today. Popular pipe materials for sewer lines are metal and plastic. Metal pipes are tough and can withstand hydraulic pressure, but it’s very prone to rust and corrosion. Most metallic sewer pipes don’t even reach their estimated lifespan because of the extreme degradation of the pipes. Plastics on the other hand are pretty much invulnerable to corrosion but are not durable. Epoxy resin is very durable and is usually estimated to last for 80-100 years. Apart from that, epoxy resin is able to withstand and corrosion. It obviously doesn’t have any problem with rusts since it doesn’t contain any metals.
