What is Pipe Relining and How Does it Work?

Introduction to pipe relining

Drain pipe relining is a no-dig method for repairing damaged pipes, eliminating the need for excavation. Plumbers and drainage specialists use it as a contemporary alternative to traditional pipe replacement, lining the interior of the existing structure.

This technique involves inserting a resin-coated liner into the existing pipe through an access point, such as a manhole. The liner hardens, efficiently crafting a new lining within the host pipe, regardless of the extent damage may appear. This technique restores pipe structure and flow without digging trenches or damaging landscaping.

Pipe relining adeptly tackles common plumbing problems, including tree root intrusion, corrosion, and cracks, as well as resolving blockages. Pipe relining is ideal if you’re seeking a quick, less disruptive, and cost-effective alternative to drain replacement. Relined pipes also have a long service life and prevent the need to dig pipe trenches.

As leading Sydney plumbers, Pennant Hills Plumbing specialises in prompt trenchless pipe repairs, swiftly addressing plumbing issues. Our team delivers comprehensive pipe relining services, expertly assessing damage, detecting leaks with CCTV, and executing relining with minimal impact on your property.

Why is pipe relining the best method for modern pipe repair?

The pipe relining process involves several key steps:

1. Inspection - A drain camera evaluates the damage within the pipe, identifying blockages or other hindrances to determine necessary repairs. This CCTV inspection ensures the technician can plan the repair accordingly.
2. Cleaning - High-pressure water jets or compressed air remove accumulated debris and sediment, preparing the pipe for relining.
3. Resin Impregnation - A felt liner soaked in a two-part epoxy resin is inserted into the damaged pipe through an access point and then cured in place. The liner covers the interior surface area.
4. Curing - The epoxy resin is solidified using hot water, UV light, or ambient curing methods. As it hardens, it forms a smooth, seamless new pipe lining within the old pipe.
5. Final Testing - Video inspections and pressure tests confirm the relined pipe’s integrity and flow efficiency. We thoroughly re-inspect any issues to guarantee they meet our high standards.

This trenchless technique ensures undisturbed landscapes, making it ideal for residential and business properties as it requires no digging. The resin solidifies to forge a sturdy, long-lasting lining that renews the structural integrity and flow capacity of an aged sewer line. Pipe relining can be faster, cleaner and less disruptive than traditional pipe replacement methods.

The pipe relining process step-by-step

Here is an overview of the key steps involved in relining a damaged pipe:

1. Inspection - A camera inspection is conducted through the pipe to ascertain damage and blockages. This allows the plumber to confidently plan the repair, to make sure they know precisely what they are doing.
2. Cleaning - High pressure water jets scour the pipe interior to remove debris and buildup for optimal lining conditions.
3. Resin Impregnation - A felt liner saturated with epoxy resin is inserted into the pipe via an access point.
4. Curing - The resin hardens through various methods, including ambient temperature, hot water steam, or UV light. This hardens the resin into a smooth new pipe lining.
5. Testing - Cameras and pressure tests check for leaks, integrity, and flow. Any hurdles can be resolved before jobs can completed with efficiency and precision.

Relining stands as an eco-friendly, minimally invasive solution your pipe function restoration needs. It minimises excavation and preserves the landscaping of your home or business.

Replacement would have taken 2 weeks and cost over $100,000 more in excavation, new materials, and restoration.

In residential settings, there is no need for replacing old pipes, so front yard trees and gardens remain untouched. Backyard pools, patios, and structures also remain fully intact.

• Concrete - Concrete pipes are prone to cracks and damage over time. Relining provides a structural reinforcement and barrier inside against further deterioration.
• Clay - An older material still found in many drainage systems. Relining rejuvenates old clay pipes from the inside out.
• Cast iron - Cast iron pipes are durable but eventually succumb to rust and corrosion. Relined cast iron pipes can last for decades.
