Is Pipe Patching The Same As Pipe Relining?
Pipe patching and pipe relining are terms often used interchangeably in the plumbing industry, leading to some confusion among homeowners and property managers.
While they stem from similar technological advancements in repairing pipes without the need for extensive excavation, there are nuanced differences worth understanding. This article delves into these distinctions, shedding light on when and why one might be preferred over the other.
Understanding the Technology
At their core, both pipe patching and pipe relining involve the use of a resin-saturated liner to repair damaged sections of pipe. This liner, once in place, is expanded to adhere to the interior walls of the existing pipe, effectively creating a “pipe within a pipe.” The resin then cures in place, sealing off leaks, covering cracks, and restoring the structural integrity of the pipe. This trenchless rehabilitation method offers a less invasive alternative to traditional pipe replacement, minimizing disruption to the property and the environment.

Pipe Patching: A Closer Look
Pipe patching is typically employed for localised repairs, focusing on specific areas of damage within a pipe system. Think of it as a targeted approach, akin to placing a band-aid on a small cut. This method is ideal for fixing isolated issues, such as a single crack or a small section of pipe that has been compromised. The patching process involves inserting a patch—essentially a short piece of liner—directly into the damaged area, where it adheres to the pipe wall and cures to form a durable seal.
Pipe Relining: The Broad Approach
Pipe relining, on the other hand, is used for more extensive repairs and can be applied to longer sections of pipe, sometimes encompassing the entire length.
This method is akin to giving the pipe system a new lease on life, addressing widespread damage or degradation.
Once the pipe is prepared, the new lining, often made of a resin-saturated felt tube, is inserted and inflated. The resin then hardens, creating a new pipe within the old one. This new pipe is resistant to leaks and root intrusion, and has a lifespan comparable to that of new pipes. The process is less invasive than traditional pipe replacement, as it requires no digging or destruction of property.
Key Differences
While the underlying technology is similar, the main difference between pipe patching and pipe relining lies in the scale and scope of their application:
- Application Scope: Pipe patching is suited for small, localized repairs, whereas pipe relining is designed for comprehensive, lengthier repairs.
- Cost-Effectiveness: Pipe patching can be more cost-effective for minor damage, as it targets specific areas rather than the entire pipeline.
- Time and Disruption: Generally, patching is quicker and causes less disruption, given its localised nature. Relining, while more invasive, avoids the significant excavation and disruption associated with traditional pipe replacement.
Choosing Between Pipe Patching and Relining
The decision between pipe patching and relining depends on several factors, including the extent of the pipe damage, the specific conditions of the site, and budget considerations. A professional assessment by a qualified plumber, such as those at Jet Plus Plumbing, is crucial in determining the most appropriate approach.
The process involves several steps. Firstly, the damaged area is identified using CCTV inspection. Once the problem area is located, it is then cleaned with hydro jetting and prepared for the reline or patch.
A specially designed patch, coated with a resin, is then inserted into the pipe and positioned over the damaged area. The resin hardens, effectively sealing the damage and restoring the pipe’s functionality.
Can Pipe Relining Repair Any Broken Pipe?
It’s an excellent solution for fixing isolated instances of corrosion or small holes. However, for more extensive damage or for pipes that are severely deteriorated, other methods such as pipe relining may be more appropriate. Understanding these nuances is key to making informed decisions about your
It’s important to note that pipe patching is not a one-size-fits-all solution. The suitability of this method depends on the type and extent of the pipe damage.
FAQs About Pipe Patching and Pipe Relining
- What size pipes can be relined in Australia?
In Australia, pipe relining can accommodate a wide range of sizes, from as small as 40mm in diameter up to 450mm. - Is it necessary to reline the entire pipe, or can just a section be relined?
Both options are available. You can either reline a specific section of the pipe using sectional relining methods or the entire pipe using inversion lining methods, depending on the damage extent. - What is the typical cost for pipe relining?
Costs can vary based on several factors including the pipe’s diameter, access difficulty, the number of junctions, and the length of relining required. Accurate quotes are provided after a detailed consultation. - Can a collapsed pipe be relined?
Yes, pipes that are partially or completely collapsed can often be relined. For fully collapsed pipes, robotic cutting might be employed to clear the blockage before relining. - Is pipe relining considered a permanent fix?
Absolutely, pipe relining is not a temporary solution but a long-term one, with materials that can last over 50 years and companies often offering guarantees of up to 35 years - Can you reline pipes made from any material?
Yes, pipe relining can be applied to a variety of pipe materials including PVC, Copper, Cast Iron, Concrete, and Clay Pipe. - How long does it take to install pipe relining?
The installation typically can be completed within a day, starting in the morning and finishing by the afternoon. - Does pipe relining require excavation?
No, pipe relining is a trenchless technology, often requiring no excavation as access is gained through existing inspection ports or sometimes by temporarily disconnecting fixtures like toilets. - What kind of pipe damage can be repaired with relining?
Relining can address a wide range of issues, including tree root invasions, cracks, burst pipes, and leaks. However, the pipe must be cleared of blockages before relining can proceed - What are the signs indicating you might need pipe relining?
Signs include foul odors, visible cracks or leaks, slow drainage, or unusual noises coming from your plumbing system, indicating potential sewer pipe damage
