5 Key Facts About Pipe Relining

pipe-relining solvedIt is said that pipe relining, also called as cure in place pipe (CIPP) patching, is a process that uses newer, smaller-diameter pipes that are fitted into the older and larger-diameter defective pipes without the need of digging. Here, the reasons why this process is used and opted by most Australians according to the plumping and drainage industry are highlighted.


  1. Convenient– To accurately assess the problem, this method will send a closed-circuit television (CCTV) camera down to the existing drains to see its actual condition, what causes the blockage and if it is suitable for relining. If it is confirmed that relining is needed, a pipe liner coated with epoxy is placed within the faulty sewer line. The bladder is then inflated by using a compressed air that enables the liner to mould to the existing pipes, thus filling cracks, holes or any voids in the pipeline.
  2. Cost efficient – Since it does not need to do extensive excavation, it will largely lower the cost of the rehabilitation project. Once it is installed, drains and sewer can readily be used, which is great in a business that cannot afford any downtime and for homeowners who don’t want any disruption to their daily routine. It also eliminates the possible damage of your gardens, driveways, roads or even homes/buildings/factories during the whole process.
  3. Quick turnaround time – Its installation can be done anytime and finished in a few hours or within one day unlike the traditional approach that requires Council or Water Authority approval and involves destructive digging that may take several days to remove the older pipes and then replaced it with the new one.
  4. Durable – The materials used in this process are environmentally friendly and scientifically tested such as epoxy, silicate, polyester, vinyl ester and resin which are usually a lot stronger than the current polyvinyl chloride (PVC) replacement and estimated to last for more than 50 years. Studies also found out that these materials can stand every corrosive environment.
  5. Double Protection – It is a joint-less product, so it ensures that no tree roots will infiltrate back into the pipe and block the drains again.

In addition, companies also claimed that the liner that will be used in the relining process can be custom made and can repair 90 degree bends in pipes and works also in 50 to 250 millimeter pipes with the maximum length of over 50 meters. It is also suitable to repair stormwater, pool and other types of pressure pipes. It gives the benefit of a new system that is similar to a complete renovation of a drain or a sewer system without several days of digging.

The facts indeed showed that the pipe relining is an excellent and reliable way to resolve any domestic and commercial drainage and sewer problems among Australians compared to the traditional pipeline replacement method which is expensive and involves long and destructive excavation.
