What is Pipe Relining? | Understanding the Pipe Relining Process

Pipe relining is a modern, innovative solution for repairing damaged pipes without the need for extensive excavation. This trenchless technology has revolutionised the plumbing industry by offering a less invasive, cost-effective, and durable alternative to traditional pipe replacement methods.

Overview

In this article, Plus Plumbing experts have explained the intricacies of pipe relining, exploring its process, benefits, and applications in pipe repair. By the end, you will have a comprehensive understanding of how pipe relining works and why it is becoming the preferred choice for many homeowners and businesses.

What is Pipe Relining?

Pipe relining, also known as Cured-In-Place Pipelining (CIPP), is a method of repairing existing pipelines by inserting a new liner inside the old pipe. This liner is coated with a special resin that hardens to form a new, durable pipe within the old one. The process is designed to fix various issues such as cracks, leaks, and root intrusions without the need for digging up the entire pipeline.

Key Components of Pipe Relining

The following are the key components of pipe relining outlined by Plus Plumbing experts:

Flexible Resin-Coated Liner: The liner is typically made of polyester or fibreglass and is saturated with a resin that hardens over time.
Epoxy Resin: This is the material used to coat the liner, which hardens to form a new pipe within the old one.
Bladder: A bladder is used to inflate the liner and press it against the walls of the existing pipe until the resin cures, ensuring a reliable pipe lining.

The Pipe Relining Process

The pipe relining process involves several steps, each crucial for ensuring a successful repair. Here is a detailed look at each stage outlined by Plus Plumbing experts:

1. Initial Assessment

Before any work begins, professionals assess the plumbing network to determine the extent of the damage and whether the pipe is a suitable candidate for relining. This often involves using a drain camera to inspect the interior of the pipes.

2. Cleaning the Pipe

The next step is to clean the existing pipe thoroughly. This is usually done using a hydro-jetting procedure, which removes debris, roots, and other blockages. Cleaning is essential to ensure that the liner adheres properly to the pipe walls. Plus Plumbing experts make sure that this process is done efficiently.

3. Preparing the Liner and Bladder

Once the pipe is clean, a customised liner and bladder are prepared according to the dimensions of the affected pipe. The liner is then soaked in high-quality epoxy resin.

4. Inserting the Liner

The resin-coated liner is inserted into the damaged pipe using specialised equipment. The bladder is placed inside the liner in an uninflated form. The liner is then positioned correctly using a drain camera.

5. Inflating the Bladder

The bladder is inflated, pressing the liner against the walls of the existing pipe. This ensures that the resin-coated liner conforms to the shape of the old pipe.

6. Curing the Resin

The resin is then cured using heat, steam, or ultraviolet light, depending on the specific method used. This hardens the resin, forming a new, durable pipe within the old one.

7. Final Inspection

After the resin has cured, the bladder is deflated and removed. A final inspection by the Plus Plumbing team is conducted using a CCTV camera to ensure that the liner has been installed correctly and that the pipe is fully functional.

Inside Plus Plumbing

Craig, a homeowner in Castle Hill, was facing a major plumbing issue with his sewer pipe, located beneath his concrete driveway. The roof of the pipe was broken, and the side walls were cracked. Other plumbers advised that the only solution was to dig up the driveway, which was less than two years old, to replace the pipe.

Craig contacted Plus Plumbing for a second opinion, hoping for a less invasive solution. After inspecting the damage, we recommended pipe relining. Plus Plumbing was successful in restoring the pipe to like-new condition. Craig was thrilled with the outcome. We saved his driveway from being destroyed and significantly reduced the overall cost of the repair. This project is a great example of how Plus Plumbing offers smart, cost-effective solutions to our clients’ plumbing problems.
