PIPE RELINING MELBOURNE
Fix cracked, broken, or tree-root-damaged pipes without digging up your yard, driveway, or garden. DemRev connects you with Melbourne’s best pipe relining specialists — backed by up to 50 years warranty.
A NEW PIPE INSIDE YOUR OLD ONE
Pipe relining is a trenchless technology that repairs damaged underground pipes from the inside — without excavation. A flexible, resin-saturated liner is inserted into your existing pipe, inflated to fit the pipe’s shape, and cured to form a rock-hard new pipe within the old one.
The result is a seamless, joint-free pipe that’s actually stronger than the original. It’s resistant to tree root intrusion, corrosion, and cracking — and it comes with a warranty of up to 50 years.
For Melbourne homeowners dealing with recurring blocked drains, sewage smells, slow drainage, or tree root problems, pipe relining is often the smartest long-term solution — saving thousands compared to traditional excavation and replacement.
HOW PIPE RELINING WORKS
CCTV Pipe Inspection
A high-definition camera is fed through your drainage system to identify exactly where the damage is, what’s causing the blockage, and the overall condition of your pipes. You’ll see the footage in real time.
High-Pressure Cleaning
Before relining, the pipe is cleared of all debris, tree roots, scale, and grease using a high-pressure water jetter. This ensures a clean surface for the liner to bond to.
Liner Preparation
A flexible felt or fibreglass liner is cut to the exact length needed and saturated with a two-part epoxy resin. The liner is calibrated to your pipe’s diameter for a precise fit.
Insertion & Inflation
The resin-coated liner is inserted into the pipe through an existing access point (usually a drain opening or inspection shaft). It’s then inflated with air pressure so it presses firmly against the pipe walls.
Curing
The resin cures and hardens — either at ambient temperature (4–6 hours) or with UV light or hot water for faster results (1–2 hours). Once cured, the liner becomes a rigid, structural pipe.
Final CCTV Inspection
A second camera inspection confirms the reline is perfect — smooth, sealed, and free of defects. You receive before-and-after footage and a warranty certificate for your records.
PIPE RELINING VS TRADITIONAL EXCAVATION
| Factor | Pipe Relining | Traditional Dig |
|---|---|---|
| Disruption to property | Minimal — no digging | Major — trenches through yard, driveways, landscaping |
| Time to complete | Usually 1 day | 3–7 days plus restoration |
| Cost | 30–50% less overall | Higher — includes excavation, backfill, restoration |
| Warranty | Up to 50 years | Typically 10–15 years |
| Tree root resistance | Excellent — joint-free | Roots re-enter at joints |
| Pipe strength | Stronger than original | Same as original |
| Property restoration needed | None | Landscaping, concrete, paving |
TYPES OF PIPES WE RELINE
Modern relining technology works on virtually all pipe materials and sizes found in Melbourne homes and businesses.
Clay & Terracotta
The most common pipes in Melbourne homes built before 1970. Prone to cracking, root intrusion at joints, and collapse. Ideal candidates for relining.
PVC & Plastic
Found in homes from the 1970s onwards. While durable, PVC pipes can crack from ground movement, poor installation, or heavy loads above the pipe.
Cast Iron
Common in older Melbourne homes and commercial buildings. Cast iron corrodes from the inside over decades, causing rough surfaces that catch debris and cause blockages.
Concrete & Earthenware
Found in stormwater drains and older sewer mains. These large-diameter pipes respond well to relining and can be repaired without disrupting roads or driveways.
Pipes from 50mm to 600mm in diameter can be relined. Our specialists handle sewer drains, stormwater pipes, downpipe connections, and junction repairs.
COMMON WARNING SIGNS
🔁 Recurring Blocked Drains
If you’re calling a plumber every few months to clear the same drain, the pipe itself is likely damaged.
🌳 Tree Roots in Pipes
Roots seek out moisture at pipe joints. Relining eliminates joints entirely, permanently blocking root entry.
💧 Slow Draining Fixtures
Sinks, showers, or toilets draining slowly often indicate a partially collapsed or root-blocked pipe downstream.
😷 Sewage Smell
Cracked pipes can leak sewer gas into your yard or even inside your home through cracks in the sub-floor.
🌊 Damp Patches in Yard
Unexplained wet spots, lush patches of grass, or sinkholes can indicate a leaking underground pipe.
🐀 Pest Activity
Rats and cockroaches use broken sewer pipes as highways into your home. Sealing the pipe cuts off their access.

FREQUENTLY ASKED QUESTIONS
How long does pipe relining last?
Relined pipes have a design life of 50+ years. The epoxy resin used is extremely durable — it’s resistant to corrosion, tree roots, and chemical attack. Most reputable relining companies offer warranties of 35–50 years.
Does pipe relining reduce the pipe diameter?
The liner adds 3–6mm to the pipe wall, slightly reducing the internal diameter. However, because the relined surface is perfectly smooth (unlike corroded original pipes), water flow actually improves in most cases.
Can you reline pipes under a house or driveway?
Absolutely — that’s one of the biggest advantages. Pipes under slabs, driveways, landscaping, and buildings can all be relined without any excavation. The liner is inserted from an access point and cured in place.
Is relining approved by Melbourne Water and councils?
Yes. Pipe relining is an accepted repair method compliant with Australian Standards (AS/NZS 2566.1). All work is carried out by licensed plumbers and meets Melbourne Water and local council requirements.
What if my pipe is completely collapsed?
If the pipe has fully collapsed with no internal passage remaining, relining may not be suitable and excavation might be required. A CCTV inspection will determine whether relining is viable. In many cases, even severely damaged pipes can be relined.
