What is Pipe Relining and How Does it Work?
Pipe relining, a trenchless technique, repairs pipes by using a resin-impregnated liner that molds to the pipe’s interior as it hardens, effectively mending damaged sections.
This technique is ideal for common pipe issues faced by many Marrickville homes and businesses, like invasive tree roots or deterioration from age. Instead of expensive and disruptive excavation, pipe relining restores pipes to like-new condition from the inside-out.
Relining starts with a camera inspection to spot pipe faults, followed by curing and bladder removal to leave behind a restored pipe.
An inflatable bladder secures the tube against the pipe interior, while UV light or steam solidifies the resin into a firm, even coating.
Epoxy resin is vital in pipe relining for its role in sealing cracks and forming a durable new pipe within the old infrastructure.
The Importance of Epoxy Resin in Pipe Relining
Epoxy resin is the key ingredient we would say makes pipe relining an effective and long-lasting repair solution. Its superior bonding strength enables it to seal cracks and adhere to damaged pipe walls for an extended lifespan.
When saturated into the liner sleeve and cured in place, the resin hardens into an exceptionally durable pipe material that can withstand years of water pressure and usage. Due to its flexibility, epoxy allows the repaired pipe to adapt to soil movement without sustaining damage.
The superior properties of epoxy allow relined pipes to often surpass the flow capacity and functionality of the original pipes. Whether fixing root intrusions or deterioration issues, epoxy resin delivers a seamless, ‘cured-in-place’ pipe repair for the residential and commercial pipes of Marrickville.
Epoxy resin forms a secure bond with stormwater and sewage pipes, effectively sealing leaks without the need for excavation. It protects properties from water damage, prevents contamination, and reduces surface disruption across the neighbourhood.
When combined with modern pipe relining techniques, versatile epoxy resin offers the ideal solution for restoring Marrickville’s ageing or damaged plumbing infrastructure.
Cleaning and Preparing Pipes for Epoxy Resin Application
Before applying epoxy resin, the damaged pipe must be thoroughly cleaned and prepared to ensure proper bonding and curing. Marrickville Plumbing ensures meticulous removal of grease, oils, sludge, mineral deposits, and debris from the interior pipe surface for optimal preparation.
High-pressure water jets and specialised tools are used to meticulously clean pipes, ensuring the removal of all contaminants. This thorough cleaning process ensures cracks and faults in the pipes are opened up, allowing for complete resin penetration and sealing. It also creates the ideal surface for the resin to adhere to.
Each pipe section is methodically cleaned to an almost-new condition, with particular focus on areas that need extra attention.
By thoroughly cleaning and preparing pipes before epoxy application, we ensure the resin cures into a seamless, watertight lining that secures to the inner walls and withstands pressure for decades.
Applying Epoxy Resin to Create a New Pipe Lining
Once the damaged pipe interior has been thoroughly cleaned, Marrickville Plumbing’s experts begin applying liquid epoxy resin to start forming the new internal lining.
We carefully measure the pipe needs in terms of dimensions and select an impregnated polyester or fibreglass calibration tube of the appropriate length and diameter. The calibration tube, saturated with unhardened resin, serves as the flexible material for the relining process.
Special application machinery inserted into the damaged pipe carries the calibration tube, protecting it from tears or gaps. An inflatable rubber bladder presses the tube against the pipe walls, ensuring there are no air pockets.
After coating the pipe’s surface, the epoxy resin hardens through exposure to curing lights or steam. This creates a smooth, jointless lining bonded securely to every contour and crack. We remove the bladder once the resin has hardened, fusing the textile tube into a durable epoxy layer.
The team meticulously monitors pressure and curing times to ensure thorough resin saturation and proper adhesion, with clear explanations provided throughout the process. The result is a seamless pipe lining that restores flow capacity and underground structural integrity.
Curing the Epoxy Resin Liner
Curing is the process that hardens the liquid epoxy resin into a solid, watertight pipe lining after application. Controlled heat from steam or hot water systems is used to expedite the curing process. Ultraviolet light can also cure the resin quickly where access allows.
The heat triggers the resin’s transformation from a viscous liquid into a hard, durable material that permanently fuses to the pipe’s interior. Our expert monitors temperatures and cure times to optimise the resin’s hardness, strength, and flexibility.
The curing phase bonds the resin to every surface crack and cavity, sealing the pipe completely. The surrounding textile liner also becomes integrated with the pipe walls, creating a seamless repair, as our experts explain each crucial step. Quality checks confirm the liner is fully cured before restoring normal water flow.
This process swiftly restores pipes to a condition that is often superior to their original state, benefitting homes and businesses alike.
Cutting and Final Inspections of the Relined Pipe
After the epoxy resin liner has fully cured, the final step is cutting it to restore service line connections and junctions before a final inspection.
Remote cameras and precision tools allow our technicians to reopen blocked sewer connections without harming the newly lined pipe, followed by a thorough clean-up. Cut edges are smoothed to prevent flow disruption and debris accumulation.
After relining, a detailed video inspection is conducted to confirm the resolution of blockages and other identified issues.
These finishing touches and quality checks validate that the epoxy resin liner meets strict industry standards. Upon completion of each relining job, we issue repair certificates to guarantee client satisfaction with the warranty for parts and labour. Ongoing pipe maintenance plans are also available for continued peace of mind.

The Benefits of Using Epoxy Resin for Pipe Relining
Using epoxy resin for pipe relining offers numerous benefits over traditional pipe replacement methods for residential and commercial plumbing systems in Marrickville.
The key advantages of epoxy relining include:
- Less invasive – By restoring pipes from the inside-out, it avoids major property damage or landscaping disruption.
- Faster repairs – The efficiency of our process is notable, as curing the resin lining typically takes only a few hours, a significant reduction from the several days traditional methods require.
- Lower costs – Pipe relining saves approximately 60% compared to full pipe replacement.
- Longer lifespan – Epoxy linings seal cracks and last for decades.
- Increased flow – Smooth resin coatings optimise drainage capacity.
- Added strength – Epoxy seals and reinforces pipe walls against future damage.
- Environmentally safe – No dig-related carbon emissions or waste products.
Marrickville Plumbing’s effective use of epoxy resins enables quick and cost-efficient restoration of both corroded and root-intruded pipes. Contact us today for comprehensive plumbing services to evaluate your property’s pipe condition and relining suitability.
Environmental Considerations for Epoxy Resins
Epoxy resins are highly durable materials that strengthen pipes for decades. However, some environmental issues may arise with improper disposal after relining work is complete.
At Marrickville Plumbing, we take a sustainable approach. Our epoxy products utilise greensafe curing agents with low VOC emissions. We collaborate with resin suppliers to recycle calibration tubes and liner materials via takeback programs.
During onsite relining, we capture and safely contain any excess resin or runoff. We employ proper PPE to protect technicians and the public from unnecessary exposure.
We submit all resin products for extensive quality testing before use to validate environmental standards.
With conscientious processes applied start to finish, pipe relining with epoxy resins can be an eco-friendly repair method. Our team works diligently to preserve the wellbeing of Marrickville homes while restoring pipes in the most sustainable way possible.
