How do you define Pipe Relining?

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

Here’s how it works:

A technician cleans the pipeline with high-pressure jetting or mechanical cleaning.
Then, they apply epoxy resin made of polyester or fiberglass liner inside the pipeline.
The liner gets cured to form a brand new inner lining in the pipeline that’s as durable as a new one.

Pros of Pipe Relining

Time-efficient: It generally takes about 2 to three hours for the entire procedure compared to excavating several days with traditional pipe replacement methods.
Cost-effective Since there is no excavation or removal necessary in pipe relining work It can save you nearly half of the amount you be paying for conventional repairs.
Durability – The new liner made by pipe relining could last for up to 50 years!

The cons of Pipe Relining

Not recommended for extremely damaged pipes - If you have significant damage such as cracks, collapses, or joints that are misaligned 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 the collapsed pipes as well as extremely damaged ones due to age or neglect.

The following steps are typical of traditional replacements for pipes:

An excavation team digs access to the deteriorated underground pipe.
The old pipeline is detached and dug out producing much debris which needs to be removed.
They then install the new pipeline on top of the previous one.

Benefits of Pipe Replacement

Suitable for severely damaged pipes If you have to replace pipes with significant damage or corrosion, pipe replacement is the best solution.
Long lifespan – The new pipeline replaced with pipe is long-lasting (75 to 100 years) which makes it a great option for homeowners looking for an ongoing solution.

Pros and Cons of Pipe Replacement

Extraction work that is costly for pipe replacement could be long and costly.
The process is time-consuming. Traditional pipe replacements could take several 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 replacement or relining your pipes mostly depends on the level of damage caused. If your pipes are suffering from small damages, like cracks or leaks that are minor, replacing them is likely to be the better option since it’s less expensive and is also faster than traditional replacements.

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