What is Pipe Relining?

Pipe relining, also known as Cured-In-Place pipe (CIPP) Lining is a state of the art repair procedure that provides a cost-effective, fast solution for repairing damaged pipelines.

Here’s how it is done:

  1. Technicians clean the pipeline with high-pressure jetting or mechanical cleaning.
  2. Then, they place epoxy resin made from fiberglass or polyester liner to the existing pipeline.
  3. The liner is cured and forms a new liner within the old pipeline, which is just as strong as a brand new one.

Benefits Pipe Relining

  • Time-efficient – It usually takes between 2 and three hours in order to finish the entire procedure, compared to excavating for several days with traditional methods of replacing pipes.
  • Cost-effective because there is no excavation or removal required in pipe relining, it can save almost half of the price you’d pay for traditional repairs.
  • Durability – The new liner formed by pipe relining can last for 50 years!

Cons of Pipe Relining

  • Not suitable for severely damaged pipes - If there are significant damages like collapses, cracks, or misaligned joints in your sewer line then pipe relining might not be feasible.

What is Pipe Replacement?

Pipe replacement involves digging up portions of the yard/sidewalk/driveway where underground pipes are located. These areas could contain broken pipes, or very damaged ones due to negligence or aging.

The following steps are typical of traditional pipe replacements:

  1. An excavation team digs access to the deteriorated underground pipe.
  2. The old pipeline is detached and dredged out, producing a lot debris which needs to be removed.
  3. Then, they put in a new pipeline in place of the one they had previously installed.

Benefits of Pipe Replacement

  • Perfect for severely damaged pipes In the event that you need to replace pipes that have significant corrosion or damage, pipe replacement is the most effective option.
  • Longer life span – The new pipeline that is installed by pipe replacement has a lengthy lifespan (75 to 100 years) which makes it a great choice for homeowners in search of an ongoing solution.

Cons of Pipe Replacement

  • It is expensive – Excavating work required for pipe replacement can be long and costly.
  • The process is time-consuming. Traditional pipe replacements can take a few weeks based on the nature of the project and the depth of excavations that are required.

Which one should you select?

The choice between relining or replacing your pipes mostly is contingent on the amount of damage caused. If your pipes suffer minor damages like cracks or minor leaks, the relining process is probably the better option since it’s less expensive and faster than replacement of pipes using traditional methods.

However, if you have severe damage, such as collapses or broken pipes the best option is traditional pipe replacement although it may be more expensive and takes longer.
