The term "pipe relining" is used to describe the process of repairing pipes.

Pipe relining, also known as Cured-In-Place pipe (CIPP) Lining is a cutting-edge repair method that provides a cost-effective, rapid solution for the repair of damaged pipelines.

Here’s how it is done:

  1. A technician cleans the pipeline by using high-pressure water jetting or mechanical cleaning.
  2. Then, they place epoxy resin made of polyester or fiberglass liner inside the existing pipeline.
  3. The liner is cured, creating a new inner lining in the old pipeline that’s just as strong as a brand new one.

Pros of Pipe Relining

  • The process is time-efficient, taking just 2 to 3 hours of time to accomplish the whole process compared with excavating for days in traditional pipe replacement methods.
  • Cost-effective because no excavation or removal is necessary in pipe relining work, it can save almost half of what you would pay for traditional repairs.
  • Durability – The lining made by pipe relining could last for 50 years!

The cons of Pipe Relining

  • Not suitable for very damaged pipes. If there are major damages such as cracks, collapses, or joints that are misaligned in your sewer line then pipe relining is not a possibility.

What is Pipe Replacement?

Pipe replacement involves digging up portions of the yard/sidewalk/driveway where underground pipes are located. These areas could contain damaged pipes, or highly corrosion-prone ones, due to the effects of time or neglect.

The following steps make up the majority of traditional pipe replacements:

  1. An excavation crew digs access to the decayed underground pipe.
  2. The old pipeline is detached and dredged out, producing a lot debris that requires disposing of.
  3. Then, they put in a new pipeline in place of the one they had previously installed.

Pros and Cons of Pipe Replacement

  • It is suitable for pipes with severe damage - When you need to replace pipes that are suffering from significant corrosion or damage, pipe replacement is the ideal solution.
  • Long life – The brand new pipeline installed through pipe replacement has a lengthy lifespan (75 bis 100 years) making it an ideal solution for homeowners who want the best solution for their home.

Pros and Cons of Pipe Replacement

  • Extraction work that is costly for pipe replacement can be costly and time-consuming.
  • Time-consuming – Traditional pipe replacements can take a few weeks based on the nature of the project and the extent of excavation required.

Which option should you pick?

The choice between the option of relining or replacing your pipes mostly is contingent on the level of damage caused. If your pipes are suffering from small damages, like cracks or minor leaks, then it is likely that relining is the better option since it’s less costly and faster than traditional pipe replacements.

But if there are severe injuries, like breaks or collapses it is recommended to consider replacing the pipe with a traditional method, even though it will cost more and may take longer.
