Is Pipe Relining a thing?

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

Here’s how it works:

  1. A technician cleans the pipeline with high-pressure water jetting or mechanical cleaning.
  2. They then apply epoxy resin made from fiberglass or polyester liner in the existing pipeline.
  3. The liner is cured to form a brand new inner lining inside the old pipeline that’s just as robust as a new one.

Pros of Pipe Relining

  • Time-efficient – It usually takes between 2 and 3 hours of time to accomplish the whole process, as opposed to digging for days in traditional pipe replacement methods.
  • Cost-effective because there is no excavation or removal needed in the pipe relining process this method can save nearly half of the amount you pay for traditional repairs.
  • Durability – The new liner formed by pipe relining can last for up to 50 years!

Pros and Cons of Pipe Relining

  • Not suitable for the most damaged pipes - If there are significant 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. The areas may contain collapsed pipes or extremely corrosion-prone ones, due to lack of maintenance or age.

The following steps are typical of traditional pipe replacements:

  1. An excavation team digs access to the damaged 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. Then, they construct an entirely new pipeline instead of the old one.

Pros of Pipe Replacement

  • Ideal for pipes that have been severely damaged If you have to replace pipes that are experiencing significant damage or corrosion, pipe replacement is the best option.
  • Long-lasting – The latest pipeline replaced with pipe is long-lasting (75 bis 100 years) which makes it a great option for homeowners looking for an option that is long-lasting.

Cons of Pipe Replacement

  • It is expensive – Excavating work required for pipe replacement could be costly and time-consuming.
  • Long-lasting – Pipe replacements can take a few weeks based on the nature of the project and the extent of excavation required.

Which one is best for you?

The decision to choose between the option of relining or replacing your pipes is largely based on the degree of damage caused. If your pipes suffer 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 replacements.

But if there are severe damage, such as collapses or broken pipes it is recommended to consider an alternative to replacing your pipe, although it could be more costly and will take longer.
