Pipe relining, also known as no-dig pipe repair, is a revolutionary method that allows Brisbane plumbers to fix cracked or broken pipes without the need for extensive excavation. This innovative technique offers a cost-effective and minimally invasive alternative to traditional pipe replacement methods. 

Using specialized equipment and materials, pipe relining enables the repair and restoration of existing pipes from within, eliminating the inconvenience and expense associated with digging up and replacing damaged pipes. 

The Brisbane Plumbers are experts in pipe relining solutions, providing homeowners and businesses with a reliable and efficient way to address their plumbing issues.

What is Pipe Relining?

Pipe relining is a cutting-edge, no-dig pipe repair method that has revolutionized how Brisbane plumbers address damaged and broken pipes. This innovative process starkly contrasts traditional pipe replacement methods, involving extensive excavation, property disruption, and significant costs. When faced with an emergency plumbing situation, such as a broken sewer line or collapsed pipe, homeowners often dread having their yard or driveway dug up to repair the damaged pipes.


Pipe relining offers a far more convenient and cost-effective solution. Instead of excavating and replacing the entire pipe, the pipe relining process allows plumbers to repair the damaged section from within. A specially designed liner, coated with a durable resin, is inserted into the existing pipe and inflated, creating a seamless pipe-within-a-pipe. This new lining effectively seals cracks, leaks, or breaks, restoring the pipe’s integrity without disrupting excavation.

Property owners can save significant time, money, and hassle associated with traditional pipe replacement methods by opting for pipe relining. The Brisbane Plumbers specialize in this innovative technique, ensuring that even the most challenging emergency plumbing situations can be resolved efficiently and effectively.

The Pipe Relining Process

Step 1: Inspection with a specially designed camera

The pipe relining process begins with thoroughly inspecting the damaged pipe using a specialized camera. Brisbane plumbers insert this camera into the pipe to assess the extent and location of the damage, such as cracks, leaks, or tree root intrusion. This inspection helps determine whether pipe relining is a viable solution for the problem. 

Traditional pipe replacement may be necessary in some cases, such as when the pipe has collapsed or the damage is too severe. However, pipe relining is often the most effective and efficient solution for many common issues, including stormwater drains and pipes under concrete slabs.

Step 2: Cleaning the pipes

Once the inspection is complete and pipe relining is deemed appropriate, we thoroughly clean the damaged pipe. High-pressure jet cleaners remove any blocked drain build-up, grease, and sediment that may have accumulated over time. This step is crucial, as a clean pipe surface is necessary for the relining material to adhere properly. 

After cleaning, the plumbers will again use the camera to ensure the pipe is completely clean and ready for relining. This double-checking process guarantees that the new lining will be applied to a smooth, debris-free surface, ensuring optimal results.

Step 3: Preparing the new lining

In this stage, Brisbane plumbers carefully measure and size the new lining to fit the specific dimensions of the damaged pipe. The lining material, typically made of polyester or fibreglass, is impregnated with a special epoxy resin that will cure to create a durable, seamless new pipe within the existing one. 

The appropriate lining material and resin are selected based on factors such as the type and extent of the damage, the location of the pipe, and any specific environmental conditions. By choosing suitable materials, plumbers from The Brisbane Plumbers, Drainage Pty Ltd ensure that the relined pipe will provide long-lasting, reliable performance.

Step 4: Relining the pipes

With the new lining prepared, Brisbane plumbers begin the actual relining process. They place the lining into an inversion tank, which is then used to guide the lining into the damaged pipe. As the lining is fed through the pipe, it is inflated using air or water pressure. This inflation process presses the epoxy resin-coated lining against the walls of the existing pipe, ensuring a tight, seamless fit. 

The pressure is maintained for a specific duration to allow the resin to begin curing and bonding with the original pipe surface. This creates a pipe-within-a-pipe structure that effectively repairs the damage and prevents future leaks or intrusions.


Step 5: Curing the pipe

The final step in the pipe relining process is curing the new lining to create a strong, durable new pipe. After the lining is inflated and pressed against the existing pipe walls, the epoxy resin must be allowed to cure completely. Brisbane plumbers can use various methods to speed up the curing process, such as circulating hot water or steam through the lined pipe or using UV light to trigger the resin’s hardening. 

Once the resin has fully cured, a robotic cutter is deployed to reopen any junctions or branch lines that may have been covered during the relining process. This ensures that the relined pipe is fully functional and integrated with the rest of the plumbing system without significant safety risks or performance issues.

Benefits of Pipe Relining

Pipe relining is a fantastic way to fix plumbing problems without the hassle and expense of traditional pipe replacement. This method creates a durable, long-lasting pipe inside the existing one, using high quality materials like polyester, fibreglass, and epoxy resins. The relined pipe can last for over a decade, providing a reliable solution for pipe repair needs.

Compared to traditional pipe replacement, pipe relining is much more affordable. It doesn’t require digging up your property or removing old pipes, which saves time and money. This is especially helpful if the damaged pipes are under concrete slabs, driveways, or landscaped areas.


Another great thing about pipe relining is that it’s minimally invasive. We only need small access points to insert the new lining so you can go about your daily life without much interruption. After the job, they perform a final inspection to ensure the relined pipe has adequate structure and flow capacity.

The only notable disadvantage of pipe relining is that it might slightly reduce the pipe’s internal diameter. However, this is usually not a problem and can even improve flow capacity in older pipes with blockages from cast iron corrosion or tree root intrusion. The Brisbane Plumbers can use jet rodding to clear any remaining blockages and ensure your pipes work perfectly.
