Is Pipe Relining a thing?

Pipe relining, also known as Cured-In-Place pipe (CIPP) lining is a state-of-the-art repair process that provides a cost-effective and rapid solution for the repair of damaged pipelines.

  1. Technicians clean the pipeline with high-pressure water jetting or mechanical cleaning.
  2. They then apply 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 that’s just as durable as a new one.

Benefits Pipe Relining

  • The process is time-efficient, taking only 2 to 3 hours to complete the whole process compared with excavating for many days using traditional pipe replacement techniques.
  • Cost-effective - Because no excavation or removal is needed in the pipe relining process this method can save nearly half of what you would be paying for conventional repairs.
  • Durability – The new liner that is created by pipe relining may last up to 50 years!

Cons of Pipe Relining

  • Not suitable for severely damaged pipes - If there are serious damages such as cracks, collapses, or joints that aren’t aligned properly 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 sections may include damaged pipes, or highly damaged ones caused by the effects of time or neglect.

The steps below are the most traditional replacements for pipes:

  1. A team of excavation workers digs access to the deteriorated underground pipe.
  2. The pipeline was ripped off and dredged out, producing a lot debris that must be cleared away.
  3. Then, they install the new pipeline on top of the previous one.

  • Longer life span – The new pipeline installed through pipe replacement has a lengthy lifespan (75 bis 100 years) making it an ideal alternative for homeowners seeking an ongoing solution.

Cons of Pipe Replacement

  • It is expensive – Excavating work required to replace pipes can be time-consuming and expensive.
  • Time-consuming – Traditional pipe replacements could take several weeks, based on the size of the work and the extent of excavation required.

Which one is best for you?

If your pipes suffer small damages, like cracks or leaks that are minor, it is likely that relining is an ideal option as it’s less costly and also quicker than traditional replacements.

However, if you have severe damage such as breaks or collapses and breaks, you must consider replacing the pipe with a traditional method, even though it may be more expensive and will take longer.

Common Questions and Answers

What is pipe relining?

Relining a pipe is a process that creates a brand new pipe inside an existing damaged pipe. This is done by inserting a liner that is flexible into the old pipe and the process of curing it. Once it is cured, the new pipe is free of joints or seams, which enhances the structural integrity of the pipe.

How does the traditional replacement of pipes differ from relining pipe?

Traditional replacement of pipes involves physically dismantling old pipes then replacing them with new ones. Contrary to this, pipe relining does not require excavation. Instead it’s accomplished by using technology that permits repairs to pipelines without digging vast areas of land.

Which method is cheaper - liner relining or conventional pipe replacement?

Relining pipelines typically costs less than traditional methods for pipeline repair as there are no expenses related to excavation or other methods necessary for removing and replacing old pipes.

Certain types of pipes can be successfully relined. Your plumber will need to examine your situation to determine if it is feasible to line your particular type of pipes. However, the majority of current pipes could be fixed with this method.

How long does the process of pipe relining take?

The exact length of time needed for the procedure is contingent upon various variables like location, environment and the type of damage. However, the average pipe Relining task usually takes between 2 and 3 days based on the amount of meters require lining..
