5 Benefits of Pipe Relining
When it comes to common plumbing and drainage problems in and around the home, blocked drains and burst stormwater pipes can be among the most damaging.
A plumbing and drainage business will often consider several options, but pipe relining is widely regarded as one of the most effective.
Pipe relining offers numerous advantages that many homeowners may not be aware of. If you’re exploring ways of repairing damaged pipes and don’t want to disrupt your perfectly manicured garden with extensive excavation, consider pipe relining services.
So, What Exactly is Pipe Relining?
Before we explore the benefits of pipe relining services over the more traditional methods of drain repair, let’s first look at what it actually is.
Pipe relining has emerged as a preferred alternative to traditional pipe replacement techniques that require costly excavation. Not only is it less intrusive, preserving your landscape and structures, but pipe relining also boasts superior durability and longevity for cast iron and PVC pipes in many circumstances. It also:
- Effectively combats tree root intrusion into stormwater pipes.
- Enhances flow efficiency.
- Stands out for its time and cost efficiency.
This makes pipe relining a smart, long-term investment for maintaining the health and functionality of your home’s plumbing system.
What the Pipe Relining Method Involves
Pipe relining is an advanced, cost-effective solution to repair broken pipes without the need for extensive excavation (and the significantly higher repair costs that come with it).
This innovative technology involves drain relining specialists inserting a seamless liner into the existing, cured-in-place pipe. This layer is typically made of durable epoxy resins, which bond to the inner diameter of the pipe lining. It effectively creates a new, seamless pipe within the old one.
The pipe relining process involves not only repairing existing damage but also strengthening the original pipe itself against future problems. With its ability to fix pipes from the inside, this process represents a leap forward in plumbing and pipe rehabilitation.
With this information in mind, let’s now look closer at the many benefits of using pipe relining to repair pipes.

1. The Process is Less Intrusive
Plumbers and homeowners alike favour the pipe relining process for its minimal disruption, especially when compared to traditional pipe replacement methods.
This innovative technique uses special relining technology for repairing broken or damaged pipes beneath your property without the significant upheaval of excavating your garden or driveway. It’s particularly advantageous for sewer systems and drain pipe repairs situated under landscaped areas or buildings.
By avoiding extensive digging, the use of pipe relining technology preserves the aesthetic appeal of your property. It also significantly reduces the time and inconvenience typically associated with pipe repairs and fixing severely blocked drains. This approach to pipe lining is ideal for busy homeowners where time and minimal disruption are of the essence.
2. The Relining Solution is Long-Lasting
A key advantage of the pipe relining process is its exceptional durability and longevity. This method revitalises your existing pipelines, using high-quality epoxy resins. These materials are renowned for their strength and resilience, often extending the life of pipes beyond their original state.
As a result, relined pipe systems can withstand various environmental stresses, from invasive tree roots to soil movements.
Most plumbing companies offer extended warranties with their pipe relining solutions. This means homeowners can enjoy peace of mind, knowing their plumbing system is secure against future pipe problems. The durability and longevity offered by pipe relining make it a wise investment for anyone seeking a reliable and long-lasting solution to their pipe repair needs.
3. Stops Tree Roots in Their Tracks
A major benefit of the pipe relining process is its effectiveness in combating tree root intrusion, a common issue in sewer and drain pipe systems.
Tree roots are naturally attracted to the moisture and nutrients in pipes, leading them to infiltrate and cause damage. Pipe relining addresses this by creating a seamless, tight seal inside the existing pipe.
This barrier prevents roots from penetrating the pipes, effectively repairing them and safeguarding them against further root-related issues.
Relined pipes are much better at keeping tree roots out, which is a big plus in areas with lots of underground plants. This gives homeowners peace of mind, knowing their pipes are protected from one of the most common causes of damage. Pipe relining experts often highlight this as a key advantage over traditional repair methods.
4. Relining Sewer Pipes Can Increase Flow
One of the most significant benefits of the pipe relining process is enhanced flow efficiency. This is particularly vital for the optimal functioning of sewer and drain pipes. Over time, traditional pipes, especially older clay or corroded metal ones, can develop rough interiors that restrict water flow.
Pipe relining products solve this issue by introducing a smooth, seamless liner within the existing pipe. This new inner surface greatly reduces friction, allowing for a more efficient flow of water and waste.
It effectively nixes the problems commonly tied to blocked pipes and delivers a more consistent and reliable flow.

5. Pipe Relining is Quick and Cost Effective
The time and cost efficiency of pipe relining solutions are among their most appealing benefits. Traditional approaches to pipe repairs often involve extensive excavation, which can be both time-consuming and costly.
There’s also the additional restoration work required post-repair. By contrast, pipe relining is a much quicker process.
Eliminating the need for large-scale digging reduces both the labour hours and the machinery required. This leads to a significant further reduction in overall pipe relining costs.
In addition to the pipe relining cost being comparatively lower than conventional pipe replacement methods, the speed of the process means less disruption to your sewer line and daily life.
For those seeking a cost-effective, efficient solution for repairing sewer pipes, drain pipes, or other plumbing issues, pipe relining presents an attractive option, blending speed, efficiency, and relative affordability.
BONUS BENEFIT: Environmental Friendliness
According to pipe relining experts, an often-overlooked yet significant advantage of the process is its environmental friendliness. Traditional pipe repair methods can be quite invasive. Not only do they disrupt the landscape but can also impact local ecosystems through extensive excavation.
On the other hand, pipe relining is trenchless, meaning it requires minimal digging and thus preserves the surrounding environment. This reduced land disturbance is crucial in maintaining the natural habitat, especially in areas with rich biodiversity.
Furthermore, the durability of relined pipes means fewer repairs and replacements in the future. This leads to reduced material waste and lower carbon emissions associated with manufacturing and transportation.
Assessing the Suitability of Pipe Relining
Pipe relining is generally the first choice for repairing underground drains because it avoids excavation, but it is not suitable for every case.
Licensed plumbers inspect damaged pipes with CCTV and other specialised gear to decide whether to reline or replace. The camera survey reveals internal conditions along the entire run, highlighting breaks, tree-root penetration and structural collapse.
If the pipe is intact enough to act as a host, the plumber cleans it with a high-pressure water jet and installs a cured-in-place liner that bonds to the interior.
Completely collapsed or misshapen sections must be dug up and replaced promptly.

Do I Need a Licensed Plumber?
This question might cross your mind as you explore your drain repair options, so let’s address it now.
In short, pipe relining is not a DIY job, just as new pipe installation isn’t either. By Australian law, pipe relining is treated as regulated plumbing work.
Therefore, it must be carried out by a licensed plumber under the Plumbing Code of Australia and Australian Standard AS/NZS 3500 Plumbing and Drainage Standards.
Ignoring this law can void your home and contents insurance policy and opens up the potential for additional costly damage, so avoid the stress, mess and legal hassles that come part and parcel of DIY work and get on the phone to your local plumbing company.
