Pipe Relining, What is it and how does it work

The relining of pipes has become an increasingly popular method of rehabilitating underground piping without the need for extensive excavation or replacement. This process involves inserting a flexible liner into the existing pipe and curing it in place, essentially creating a new pipe within the old one.

One of the primary benefits of pipe relining is its cost-effectiveness compared to traditional methods of pipe repair. Excavation and replacement can be time-consuming and expensive, particularly if the problematic pipe is located under a structure or through other obstructive areas. Pipe relining eliminates the need for excavation, reducing the overall cost and time required for repairs.

Pipe relining is also an environmentally friendly option as it reduces the amount of construction waste generated during the repair process. With traditional excavation methods, large amounts of soil and debris are dug up and transported away, often causing environmental damage as well as contributing to air and noise pollution. In contrast, pipe relining only requires a small access point to be created, resulting in much less damage to the surrounding area.

Another advantage of pipe relining is its ability to improve flow capacity and durability of the pipeline. Over time, pipes can become damaged, corroded, or blocked, leading to a reduction in the flow of material through the pipeline. Relining can correct these issues by creating a smoother, more durable surface inside the pipe, which allows for improved flow.

Furthermore, relined pipes have been shown to exhibit increased resistance to future damage from external factors such as ground movement or root intrusion, making them a more long-lasting solution. This added durability can potentially save property owners money in the long run by reducing the need for frequent repairs or replacements.

However, pipe relining is not always the best option for every situation. Its effectiveness depends on a variety of factors, including the age and condition of the existing pipe, the type and severity of the damage, and the desired outcome of the repair. In some cases, excavation and replacement may still be necessary to fully address the issue.

Additionally, pipes that have been previously relined may not be able to undergo further relining due to the likelihood of reduced space inside the pipe for the liner to be installed. As a result, it is essential to have an experienced professional assess the condition of the pipe and determine the most appropriate course of action.

In summary, pipe relining provides a cost-effective and environmentally friendly solution for repairing pipelines in need of rehabilitation. It has the potential to increase flow capacity and durability while reducing the amount of waste generated during the repair process. However, it may not always be the most suitable option, and a professional assessment is necessary to determine the best course of action for each situation.
