What Is Pipe Relining?
Pipe relining is a modern, no-dig method of permanently repairing damaged, cracked or root-infiltrated drain pipes from the inside — without excavating your garden, driveway or flooring. A flexible resin liner is inserted into the damaged pipe, inflated to fit perfectly against the pipe walls, and cured to form a brand new pipe within the old one.
💡 Quick answer: Pipe relining repairs cracked, root-damaged drains without digging: a resin-saturated liner is inserted into the existing pipe and cured in place, forming a smooth structural pipe inside the old one. Driveways, gardens and floors stay untouched — and roots are permanently locked out.
⚖️ Relining vs Excavation
| 🔧 Pipe relining | ⛏️ Excavation | |
|---|---|---|
| Disruption | None — no trenches | Trenches through gardens, driveways, floors |
| Time | Usually a day | Days, plus reinstatement work |
| Best for | Cracks, root entry, most damaged sections | Fully collapsed pipes with no remaining bore |
| Aftermath | Smooth jointless pipe, camera-verified | New pipe plus landscaping and concreting bills |

The result is a seamless, jointless pipe that is actually stronger than the original — and comes with a long-term product warranty. It is the permanent solution to recurring drain problems caused by ageing or damaged pipes.
What Pipe Relining Fixes Permanently
- Tree Root Intrusion: seals pipe joints permanently so roots can never re-enter
- Cracked Pipes: cures over cracks and fractures, restoring full structural integrity
- Leaking Joints: creates a seamless, jointless interior — no more leak points
- Collapsed Sections: partially collapsed pipe sections can be relined and restored
- Recurring Blockages: eliminates the root cause of blockages that keep coming back
- Ageing Clay Pipes: breathes new life into old earthenware pipes without replacement
Pipe Relining vs Pipe Replacement
Traditional pipe replacement involves digging up the old pipe — destroying gardens, driveways, concrete paths and sometimes interior flooring in the process. Reinstatement of those surfaces often costs more than the plumbing work itself.
Pipe relining requires no digging, no garden damage, completes in one day, has no reinstatement costs, leaves you with a pipe stronger than the original, comes with a long-term warranty, and prevents tree root re-entry permanently. Pipe replacement requires extensive digging, significant garden and driveway damage, 3–5+ days to complete, often $2,000–$10,000+ in reinstatement costs, restores pipe to original strength only, and allows root re-entry at joints over time.
The Pipe Relining Process — Step by Step
- CCTV drain inspection: we camera inspect the full drain line to map damage, measure pipe diameter and length, and confirm relining is the right solution.
- Hydro jet preparation: the pipe is thoroughly cleaned with our 5000 PSI hydro jetter — removing all root material, scale and debris so the liner bonds perfectly.
- Liner insertion: a resin-saturated felt liner is inserted into the pipe and inflated using an inversion drum or pull-in-place system, pressing the liner firmly against the pipe walls.
- Curing: the resin cures and hardens — forming a rigid, seamless new pipe within the old one. Typically 1–4 hours.
- Final CCTV inspection: we camera inspect again to confirm the liner has cured correctly and the pipe is fully restored.
How Much Does Pipe Relining Cost in Melbourne?
Pipe relining costs in Melbourne's South East typically range from $500–$1,500 per metre depending on pipe diameter, depth, access difficulty and the extent of damage. A standard residential job — say, a 6-metre sewer line — typically costs $3,000–$8,000 all inclusive.
Compare that to traditional pipe replacement where excavation, pipe replacement AND reinstatement of your garden or driveway can easily reach $15,000–$25,000 for the same section. In most cases pipe relining is significantly cheaper — and faster. Every job starts with a CCTV assessment and a fixed written quote, so you know the exact pipe relining cost before deciding.

Frequently Asked Questions — Pipe Relining
Do you do pipe relining near me, and what does it cost?
Yes — we reline drains across Melbourne's outer east, the Dandenong Ranges and the Yarra Valley. Most jobs run $3,000–$15,000 depending on length and access; see our pipe relining cost guide and relining vs replacement guide, or call Jack on 0425 226 636 for a fixed price after a camera inspection.
How long does pipe relining last?
Pipe relining products carry a long-term manufacturer warranty. In real-world conditions, properly installed pipe liners typically outlast the original pipe by a significant margin — many installations are expected to last 50+ years.
Can all pipes be relined?
Most pipes 50mm diameter and above can be relined. Pipes that have completely collapsed (not partially) may require replacement. Clay, PVC, cast iron and concrete pipes are all suitable candidates. A CCTV inspection confirms suitability before any commitment is made.
Does pipe relining reduce the pipe diameter?
The liner adds a small thickness to the inside of the pipe — typically reducing internal diameter by 6–8mm. This has no practical impact on flow capacity for residential drain lines and is well within Australian standards for drainage.
Will tree roots come back after pipe relining?
No. The relined pipe is completely seamless with no joints — which is exactly where roots enter. Roots cannot penetrate the cured resin liner, making relining a permanent solution to tree root intrusion.
How long does the job take?
Most residential pipe relining jobs are completed in one day. The CCTV inspection, hydro jet preparation, liner installation and final inspection are all carried out in a single visit.
How long does pipe relining last?
Quality liners are engineered for a 50-year design life — comparable to new pipe. And because the cured liner is jointless, the root entry points that caused the original damage simply no longer exist.
Can you reline a pipe that has tree roots in it?
Yes — that’s the classic relining job. We jet the roots out first, camera the line to confirm the pipe holds its shape, then line straight over the entry cracks so roots can never get back in.
Do I need relining, or just a good drain clear?
The camera decides. If the line is structurally sound, a clear is all you need. If we find cracks, offset joints or repeat root entry, we show you the footage and quote relining in writing — no pressure, and no work without your go-ahead.
