Pipe relining is one of the best ways to fix and upgrade your pipes without the mess of digging deep trenches or tearing up your entire drainage system to install a full replacement. Modern relining is really built to last, and it can save you thousands of dollars over the life of your property.
In this blog, we’ll take a deep dive into pipe relining services, how they work, the techniques used, and why they’re often a smarter and cleaner solution than traditional dig-up repairs. If you’re dealing with ageing pipes or repeated blockages, relining could be just what your home or business needs to get your system back to full working order.
What is pipe relining
Pipe relining is a trenchless repair technique that reinforces old or damaged pipes and gives them a new lease of life by installing a new internal lining, which is just as strong and durable as the original material. With relining, the pipe doesn’t move or get pulled out. Drain specialists can simply create a new section by inserting a liner filled with resin and a deflated bladder, which expands to create a new pipe.
Sewer pipe relining is a practical option because it:
- Works without excavation, so your home’s prized spaces (garden, driveway, flooring, etc) stay untouched.
- Creates a strong ‘pipe within a pipe’ that can handle heavy usage.
- Suits all sorts of pipe sections, including drain lines, junctions, bends (and more).
- Helps fix cracks and corrosion without having to remove the pipe.
- Provides a hardy and lasting solution that reduces the need for costly ongoing repairs.
How pipe relining works (step-by-step)
We’ve already stated that a resin-filled liner is fundamental to drain relining, but there’s a lot more cutting-edge tech that goes into each stage of the process. Here’s a step-by-step installation guide for pipe relining.
1. CCTV inspection
To start the procedure, a small waterproof camera is sent into the pipe to assess:
- The location of damage
- The extent of the cracks, holes, tree root intrusion, or corrosion
- The overall condition of the drainage line
The step provides full visibility of the issue without having to play a game of “dig and look around”. By using CCTV cameras, the specialist knows exactly what they’re dealing with from the get-go. It also highlights any other issues that might have been missed by going in blind without detailed footage.
2. High-pressure cleaning
Next, the pipes are scoured clean with high-pressure water jets. Hydro jetting is great for clearing away any grease, sludge, debris, roots, mineral build-up — basically anything that’s probably accumulated and stuck to the inside over many years.
Once the pipe is clean, the drain specialist can also home in on any cracks or weak spots that were previously hidden.
3. Liner installation
Now, it’s time for the specialised liner to be inserted into the old pipe. This will be positioned to sit flush against the damaged section.
4. Liner inflation and curing
When the liner is in place, it will then be inflated using air or water pressure so it moulds against the inside of the existing pipe. The resin is then hardened using several processes, including:
- Steam
- Hot water
- UV lighting
- Ambient curing (depending on the system).
As the resin cures, it forms a brand-new pipe inside the old one, as good as new.
5. Final inspection
All that is left to do now is inspect the high-quality work. A CCTV camera is used to confirm:
- Proper alignment
- Complete curing
- Smooth flow
- No remaining defects
One that’s all done, the pipe is ready to use immediately.
What are the pipe relining techniques used by pros?
There are three main techniques that pipe relining pros in Melbourne use:
- UV-light cured relining – UV light accelerates the curing process, ideal for longer pipelines or commercial sites where downtime must be minimal.
- Heat-cured relining – steam or heated water is circulated through the liner to harden the resin quickly and evenly.
- Ambient-cured relining – resin cures naturally at room temperature, which is useful for shooter repairs or when equipment access is limited.
Why choose pipe relining over a full replacement?
You may be asking why opt for a pipe relining over something completely brand new? For most jobs, going the whole hog and replacing everything is simply unnecessary (and very expensive). But there are lots of benefits.
1. It’s significantly faster
Traditional pipe replacements are a big task and can take multiple days to complete, maybe even weeks if the excavation is tricky and runs into problems. That’s more stress and upheaval for you and your family. With pipe relining, most jobs can be completed in a single day.
2. There’s no digging or damage to your property
Everything happens below the surface with pipe relining, so everything above ground stays intact. Your gardens don’t need to be dug up and ruined, driveways remain untouched, and landscaping doesn’t need to be rebuilt in the aftermath. It’s non-invasive and much more palatable for you (and your neighbours).
With modern CCTV guiding the process, specialists can work with pinpoint accuracy.
- No need for trenches or heavy excavation equipment
- The relining team can work through existing access points like manholes.
- Footpaths, lawns, and fences also stay exactly as they are
- Even in busier commercial areas, people can walk past without disruption.
3. It’s long-lasting
Modern liners are incredibly durable and can last for generations. Just one simple upgrade with relining will give your pipes the strength to resist corrosion, cracks, tree roots, chemical damage, and other common causes of pipe failure.
4. It’s ideal for properties with difficult access
Relining works especially well in areas that might not be as easy to get to, such as:
- Narrow side paths
- Built-up areas
- Under concrete slabs
- Near older homes with fragile structures
5. It’s cost-effective in the long term
With pipe relining services, you benefit in the here and now, but you also avoid the costs of traditional repairs. You won’t have to fork out for:
- Digging
- Landscaping restoration
- Structural repairs
- Longer jobs and labour hours
There’s also the big advantage of the new liner creating a stronger pipe, which means there’s less chance of blockages plaguing your daily life.
