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

Pipe relining or Cured-In-Place Pipe (CIPP) Lining is a state of the art repair procedure that offers a cost-effective and quick solution to repair damaged pipelines.

Here’s how it will work:

  1. A technician cleans the pipeline using high-pressure water jetting or mechanical cleaning.
  2. They then apply epoxy resin made from fiberglass or polyester liner in the pipeline.
  3. The liner cures by forming a new lining within the old pipeline that’s just as durable as a new one.

Advantages Pipe Relining

  • Time-efficient: It generally takes just 2 to three hours in order to finish the whole procedure compared to excavating days in 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 the price you’d have to pay for repairs that are traditional.
  • Durability – The new liner formed by pipe relining can last for up to 50 years!

Cons of Pipe Relining

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

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 steps below are the most traditional replacements for pipes:

  1. An excavation team digs up access to the decayed underground pipe.
  2. The old pipeline has been removed and dug out, creating a lot of debris that needs to be disposed of.
  3. Then, they install the new pipeline on top of the old one.

Benefits of Pipe Replacement

  • Perfect for severely damaged pipes - When you need to replace pipes that are experiencing significant corrosion or damage, pipe replacement is the most effective option.
  • Long-lasting – The latest pipeline, which is replaced by pipe has a lengthy lifespan (75 or 100 years) which makes it a great solution for homeowners who want an option that is long-lasting.

Pros of Pipe Replacement

  • Costly – Excavation work requred for pipe replacement could be costly and time-consuming.
  • Time-consuming – Traditional pipe replacements may take weeks depending on the extent of work and the depth of excavations needed.

Which one is best for you?

The decision of either relining or repairing your pipes mostly is contingent on the extent of damage caused. If your pipes suffer from minor damages like cracks or minor leaks, it is likely that relining is the better option since it is less costly and also quicker than traditional replacements.

However, if you have severe damages like collapses or breaks it is recommended to consider conventional pipe replacement, though it may be more expensive and may take longer.

FAQ

What is the process of relining pipes?

Relining a pipe is a process which involves the creation of a new pipe within the existing damaged pipe. This is done by inserting a flexible liner inside the existing pipe, and then placing it into place. After curing, the new pipe is completely free of joints and seams, which increases its structural integrity.

How does traditional pipe replacement differ from pipe relining?

Traditional replacement of pipes involves digging up and physically taking away old pipes and then replacing them with brand new ones. However, pipe relining does not require excavation. Instead it’s carried out using technology that allows for repair of pipelines without digging large portions of land.

Which one is less expensive - the pipe relining method or traditional pipe replacement?

Relining pipes typically cost less than the traditional methods of repair of pipelines because there aren’t any costs related to excavation and other techniques necessary for removing and replacing old pipes.

Can all types of pipes be lined?

Not all types of pipes can be relined successfully. In the end, your plumber must examine your pipe to determine if it’s possible to line your specific type of pipes. But, the majority of modern pipes can be relined with this procedure.

How long will the process of pipe relining take?

The exact time required for the process is dependent on various variables like location, climate, and type of damage. However the typical Pipe Relining job typically takes around 2 days based on the amount of metres require lining..
