Pipe Relining Technology
Digging up floors, driveways, or landscaping to fix a damaged pipe is a thing of the past. MPJ Plumbing Group brings you the latest in pipe relining technology to repair underground or in-wall pipes without the mess of excavation. Serving Sydney businesses and properties, our trenchless pipe relining technique offers a fast, cost-effective, and durable solution for cracked, leaking, or root-infested pipes. Whether it’s a sewer line beneath a busy car park or a stormwater drain under a manicured garden, we can rehabilitate the pipe from the inside out, saving your property from major disruption. The result is a “like-new” pipe within the old one, fully sealed and ready to serve for decades. If you’re facing recurring blockages or have been told you need a pipe replacement, talk to MPJ about relining – it could be the ideal solution.
What is Pipe Relining?
Assessment and Cleaning
Lining Installation
We measure and create a custom resin-saturated liner that will fit the length of the damaged section. Using specialised equipment, we insert this flexible liner into the pipe and position it accurately over the affected area
Curing
Once in place, the liner is expanded (using air or water pressure) so it presses against the inner walls of the old pipe. We then cure the resin – often by circulating hot water or UV light – which hardens the liner. After curing, the liner becomes a solid, durable new pipe wall inside the old pipe.
Final Inspection
We perform a final CCTV inspection to ensure the relined pipe is smooth and free of obstructions. The ends of the liner are trimmed as needed to re-establish connections to the rest of the plumbing system. The repaired pipe is now ready for use, with a lifespan comparable to a brand new pipe.
This entire process typically can be done via existing access points like manholes or small entry pits, meaning your property’s surface remains largely untouched.
Benefits of Relining with MPJ
No Dig, No Disturbance
Trenchless repair means minimal disruption to your business and property. You won’t have to cordon off areas for excavation or endure days of loud digging work. This is especially valuable for commercial sites like restaurants, shopping centres, or hospitals where closure is costly.
Time & Cost Efficient
Pipe relining is usually faster than traditional re-piping, which means labour costs and downtime are reduced. You also save on expensive restorative work (re-landscaping gardens, repaving lots, rebuilding walls) since we don’t tear them up in the first place.
Long-Lasting Solution
The epoxy resin liners we use are extremely durable and resistant to future corrosion or root intrusion. In fact, relined pipes often come with a 20-50 year lifespan. It’s a set-and-forget fix for chronic pipe issues.
Improved Flow
The new interior of the pipe is smooth and jointless, improving flow capacity. Because there are no seams, there’s less chance of debris catching and causing new blockages. Your drains will operate more efficiently after relining.
Versatile Application
Our pipe relining works for various pipe materials (clay, cast iron, PVC) and diameters, and can navigate bends. Whether it’s a small diameter kitchen waste pipe or a large sewer main, we have liners and techniques to handle it. MPJ has relined pipes in all kinds of Sydney properties – from heritage buildings to modern high-rises – with great success.
