Is Pipe Relining a thing?

Pipe relining, also known as Cured-In-Place pipe (CIPP) Lining is a state-of-the-art repair process which offers a low-cost and fast solution for repairing damaged pipelines.

Here’s how it works:

  1. Technicians clean the pipeline with high-pressure jetting or mechanical cleaning.
  2. Then, they put epoxy resin made of fiberglass or polyester liner to the pipeline.
  3. The liner is cured to form a brand new inner liner within the old pipeline, which is just as durable as a new one.

The advantages of Pipe Relining

  • Time-efficient: It generally takes between 2 and three hours for the entire process, as opposed to digging for many days using traditional methods of replacing pipes.
  • Cost-effective - Because there is no excavation or removal necessary for pipe relining this method can save nearly 50% of the cost you’d pay for traditional repairs.
  • Durability – The new liner made by pipe relining could last for 50 years!

Con’s of Pipe Relining

  • Not suitable for severely damaged pipes. If you have significant damage like collapses, cracks, or joints that aren’t aligned properly in your sewer line, then pipe relining may not be possible.

What exactly is Pipe Replacement?

Pipe replacement involves digging up portions of the yard/sidewalk/driveway where underground pipes are located. The areas may contain the collapsed pipes as well as extremely corrosion-prone ones, due to age or neglect.

The following steps are typical of traditional pipe replacements:

  1. An excavation team digs up access to the deteriorated underground pipe.
  2. The pipeline that was previously in use is detachment and dug up, generating a lot of debris that needs to be disposed of.
  3. They then install another pipeline in place of the previous one.

Pros and Cons of Pipe Replacement

  • Ideal for pipes that have been severely damaged Ideal for severely damaged pipes – If you must replace pipes with severe corrosion or damage, pipe replacement is the best option.
  • Long lifespan – The new pipeline, which is replaced by pipe is long-lasting (75 bis 100 years) which makes it a great alternative for homeowners seeking a permanent solution.

Cons of Pipe Replacement

  • The work of excavation required for pipe replacement can be time-consuming and expensive.
  • It is time-consuming. Pipe replacements could take several weeks, based on the extent of work and the depth of excavations needed.

Which one should you choose?

The decision of the option of relining or replacing your pipes mostly depends on the degree of damage caused. If your pipes have minor damages like cracks or minor leaks, then replacing them is likely to be a more appropriate choice since it’s less expensive as well as quicker than conventional replacements.

But if there are severe damages like collapses or breaks it is recommended to consider replacing the pipe with a traditional method, even though it could be more costly and take longer.

Common Questions & Answers

What is pipe relining?

Relining pipes is a procedure that involves creating a new pipe inside an existing damaged pipe. This is done by inserting a flexible liner in the old pipe and the process of curing it. After curing, the new pipe is completely free of joints and seams which improves its structural integrity.

What does traditional pipe replacement differ from relining pipe?

Traditional replacement of pipes involves excavating and physically taking away old pipes and then replacing them with brand new ones. Contrary to this, pipe relining doesn’t require excavation. Instead it’s accomplished using technology that allows for pipe repair without digging up large areas of land.

Which method is cheaper - pipe relining or traditional pipe replacement?

Relining pipelines typically costs less than traditional methods of pipeline repair as there are no expenses related to excavation or other methods that are required to remove and replace old pipes.

Can all kinds of pipes be changed?

Not all types of pipes are relined effectively. The plumber will have to inspect your particular situation to determine whether it’s feasible to line your specific kind of pipes. But, the majority of current pipes could be repaired by this method.

How long does the process of relining pipes last?

The exact duration of the procedure varies based on factors such as location, environmental conditions and type of damage; however the average Pipe Relining job typically takes around 2 days depending on how many meters need to be lined..
