What’s Really Happening Inside Your Pipes?
When you hear “pipe relining,” it can sound a little mysterious. Homeowners often ask:
“If you’re not digging up my pipes, what are you putting in there – and will it really last?”
It’s a smart question.
After all, your plumbing is hidden behind walls and underground – and it’s something you rely on every day. If you’re paying for pipe relining, you deserve to know exactly what materials are being used, how they work, and why they’re worth the investment.
This is an ultimate guide to all things that you need to know about pipe relining materials to make informed decisions about your plumbing. What is literally going into your pipes, and why proper materials are the key to long-term durability, we have all of this covered.
We will explain to you how the installation process goes, how to be able to distinguish between low-quality and high-quality items, and how to get a clear idea of what to expect in terms of durability and efficiency. With this information, you will be equipped to prevent poor workmanship or inferior materials and maintain the plumbing of your home in the tip-top condition.
Why Pipe Relining Is Replacing Traditional Pipe Repairs in Sydney
Sydney’s plumbing network is full of ageing clay, cast iron, and concrete pipes – many over 50 years old. Combine that with shifting soils, tree roots, and heavy rainfall, and it’s no wonder that damaged pipes are a growing problem.
Traditionally, fixing these meant digging up lawns, driveways, or entire rooms of your home.
Pipe relining changed the game – allowing plumbers to create a new “pipe within a pipe” using advanced materials and techniques – no excavation required.
Done properly, pipe relining offers:
- A 50+ year solution
- Less disruption
- Faster completion (often 1 day)
- Cost savings (no property restoration required)
- Environmental benefits (preserving established gardens, paving, landscaping)
What Are Pipe Relining Materials Made From?
| Component | Purpose |
| Felt or Fibreglass Liner | Flexible tube that lines the damaged pipe |
| Epoxy or Silicate Resin | Cures the liner into a rigid, waterproof pipe |
| Calibration Tube (Bladder) | Inflates the liner during installation to ensure a perfect fit |
1. Felt or Fibreglass Liner
- Felt liner: Often used in smaller residential drains – sewer pipes (100mm–150mm)
- Fibreglass liner: Heavy-duty applications – larger stormwater drains, commercial pipes
Both liner types are engineered to:
- Be chemically resistant
- Tolerate root intrusion
- Withstand soil movement and vibration
- Maintain structural strength for decades
The liner is cut to exact length for your pipe – no one-size-fits-all shortcuts.
2. Epoxy or Silicate Resin – The Core of Pipe Relining Materials
The resin bonds the liner to your original pipe, cures rock-hard, and forms the new structural pipe.
Premium resins:
- Meet AS4020 (drinking water safety)
- Are fully resistant to household chemicals
- Stay flexible enough to handle pipe movement
- Won’t shrink, crack or peel
- Maintain smooth internal surfaces for optimal flow
At Dial Up Plumbing, we only use high-grade epoxy or silicate resins from trusted German and Australian suppliers.
Cheaper products? They may look similar – but they’re often prone to:
- Uneven curing
- Early shrinkage
- Chemical breakdown over time
In short: the resin matters most – and the right material makes all the difference.
3. Calibration Tube (Bladder)
This temporary component is used during install:
- Pressurises the liner so it bonds 100% to pipe walls
- Ensures correct shape and smooth finish
- Is removed after curing – leaving just the new pipe behind
How Pipe Relining Installation Works - And Why It Matters
Even premium pipe relining materials will fail if installed poorly. That’s why the installation process matters.
Here’s our step-by-step professional process at Dial Up Plumbing:
1: Initial Inspection & Diagnosis
- High-definition CCTV inspection
- Mapping of pipe damage
- Assessing suitability for relining
2: Pipe Preparation
- High-pressure water jetting (4,000 psi)
- Removal of roots, debris, and scale
- Ensures a clean surface for bonding
3: Liner Prep & Resin Saturation
- Liner cut to exact length
- Resin evenly impregnated – no dry spots
- Temperature-controlled handling for consistent quality
4: Liner Insertion & Inflation
- Liner inverted into pipe using air or water
- Calibration tube inflated
- Liner pressed tightly against old pipe wall
5: Controlled Curing
- Ambient cure or heated (hot water or steam)
- Typically 4–8 hours depending on pipe size
- Resin hardens into solid new pipe wall
6: Final Inspection & Sign-Off
- CCTV re-inspection
- Flow test and structural verification
- Warranty documentation provided
How Long Will a Relined Pipe Last?
-
- Expected lifespan: 50+ years
- Warranty: 50 years product, 10 years workmanship
- Resistance:
- Tree roots
- Soil shifts
- Ground vibration
- Chemical corrosion
