Pipe Relining Sydney
No dig. No mess. Fixed for life.
CCTV Diagnosis First. Epoxy Liner Inserted. AS/NZS Compliant.
Nobody wants their yard, driveway, or landscaping dug up if there’s another way to fix a damaged pipe, and most of the time, there is. Instead of excavating, we feed a flexible, epoxy-saturated liner into your existing pipe, inflate it against the pipe walls, and cure it in place. What you’re left with is basically a new pipe inside the old one. It’s a structural repair that’s fully compliant with AS/NZS 11295, usually carries a 50-year liner life, and doesn’t involve a single shovel. We do this across all Sydney suburbs on sewer pipes, stormwater drains, and downpipe connections.

What Is Pipe Relining and How Does It Work?
Pipe relining, also called cured-in-place pipe lining or CIPP, is a trenchless way to repair a damaged sewer pipe, stormwater drain, or internal drain line. We fix cracked, root-damaged, or deteriorating pipes from the inside, so there’s no digging, no torn-up garden, no ripped-out driveway or flooring.
Sewer Pipe Relining Sydney
Sewer pipe relining repairs cracked, root-damaged, or joint-separated sewer lines without excavation. We reline cracked, root-damaged, or joint-separated sewer lines without any excavation, whether that’s the main sewer line from your house to the boundary or an internal drainage stack. This is particularly common on terracotta clay pipes in Sydney’s older suburbs.
Stormwater Pipe Relining Sydney
A cracked or collapsed stormwater pipe means surface flooding and erosion around your foundations. We reline residential and commercial stormwater pipework, including 90-degree bends and T-junctions, with flexible liner systems that follow the pipe's actual shape.
Clay Pipe Relining
A lot of Sydney's older housing, particularly anything built between 1950 and 1985, still has terracotta clay drainage that's well past its working life. Clay pipes crack with ground movement, develop gaps as the mortar in the joints fails, and let roots in at every joint. Relining extends the functional life of these pipes by 50-plus years without touching the yard.
PVC Pipe Joint Repair
Even newer PVC systems can develop joint failures from ground movement, temperature changes, or a dodgy original install. If the pipe itself is fine but a joint's separated or cracked, we can do a targeted, localised reline without disturbing the rest of the system.
Root Damage Repair by Pipe Relining
Once we've jetted the roots out of a drain, the damaged spots that let them in in the first place are still there. Relining seals those entry points for good, with the cured epoxy creating a barrier roots can't get through. If you're dealing with recurring root problems, jetting plus relining is the combination that actually solves it.
CCTV Drain Camera Inspection
Every relining job starts with a camera down the line. It finds the fault, checks the pipe's condition, measures the damaged section, and confirms the liner can go in without a hitch. We also offer CCTV inspection as a standalone service if you just want a read on your pipes before deciding anything.
Post-Relining CCTV Verification
Once the liner's in and cured, we run a second camera through to confirm it's bonded properly, covers the full length needed, and hasn't reduced the internal diameter. That report goes into your job documentation and can be handed to strata managers or insurance assessors if you need it.
Is Relining the Right Call for Your Property?
Relining makes sense when a pipe’s structurally damaged but digging it up would wreck the yard, driveway, or flooring above it, or when the pipe runs under a slab, a tiled bathroom, a driveway, or a retaining wall where a normal dig-and-replace just isn’t practical or affordable.
It’s not the right call for a pipe that’s fully collapsed and too narrow for a liner to fit through, or for sections with several tight 90-degree bends close together (some limitations apply here, our CCTV inspection tells us for sure before we quote).
Pipe relining is NOT suited to:
- Fully collapsed pipes where the internal diameter is too restricted for liner insertion
- Sections with multiple 90-degree bends in very short distances (some limitations apply, our CCTV inspection confirms suitability before quoting)
Pipe relining is suited to these situations:
Cracked or split pipes
The pipe’s cracked from ground movement, root pressure, or age, but the alignment’s still intact. Relining seals it and restores structural strength from the inside.
Root-damaged pipes
Once the roots are jetted out, the joint gaps and cracks they got in through are still open. Relining seals them permanently.
Deteriorated clay or asbestos cement pipes
These don’t fail in one spot, they degrade all the way along. Relining the whole run is more practical and longer-lasting than patching every joint individually.
Pipes under concrete, tiles, or landscaping
Anywhere digging would mean tearing up and replacing a hard surface, relining sidesteps that completely.
How We Do a
Pipe Relining Job in Sydney?
- 01
CCTV Inspection and Assessment
We run a waterproof camera through the pipe to find the fault, measure the damaged section, check the internal condition, and confirm the liner will actually work here. You see the footage, we walk you through what it means, and you get a fixed price before anything else happens.
- 02
High-Pressure Cleaning
We clean the pipe thoroughly with jetting to clear root debris, silt, and anything else that'd stop the liner bonding properly. A clean pipe wall is essential for the liner to stick.
- 03
Liner Insertion, Curing, and Verification
The epoxy-saturated liner goes in and gets inflated against the pipe walls, then cured in place, either at ambient temperature or sped up with steam or UV depending on the product. Once it's cured, a second camera pass confirms full coverage and integrity, and you get the documentation, CCTV footage included, when the job's done.
What Standards Does Pipe Relining Have to Meet in Sydney?
Pipe relining in Australia sits under AS/NZS 11295, which covers material requirements for the liner and resin, how wall thickness is worked out, installation and curing procedures, pre- and post-install CCTV testing, and documentation. Our relining work complies with AS/NZS 11295 across the board, and we provide documentation referencing the standard, which matters for insurance claims, strata records, and council-regulated commercial sites.
This standard covers:
- Material requirements for the liner and resin
- Design methodology for determining appropriate wall thickness
- Installation procedures and curing requirements
- Testing and inspection requirements (pre- and post-installation CCTV)
- Documentation and reporting
Sigma Plumbing’s pipe relining work complies with AS/NZS 11295. We provide post-completion documentation referencing the applicable standard, essential for insurance claims, strata records, and council-regulated commercial properties.

What Sydney Customers Say About Our Relining Work
Rated 5.0 Stars on Google
"Sigma found root damage in our clay sewer line under the back patio. The alternative was digging up the whole patio and relaying pavers. They rellined the 7-metre section in one day, no digging, clean job. The CCTV footage before and after was impressive."
"Tree roots had cracked the sewer line running under our driveway. Sigma came out, confirmed with the camera that relining was possible, and completed the job while we were at work. Driveway untouched. Excellent outcome."
"Had cracking in the clay drain under the bathroom slab. Was dreading having to remove the tiles. Sigma showed us on camera exactly where the crack was, rellined the section, and gave us the post-job CCTV report for our records. No tiles lifted, no mess."
People Also Ask: “Why is pipe relining so expensive?”, It comes down to the specialised liner materials, the curing equipment, and the trained installation involved. But stack it up against digging, reinstating a driveway or patio, and the disruption of a traditional pipe replacement, and relining usually works out cheaper overall for anything running under a hard surface.

How Much Does Pipe Relining Cost in Sydney?
Pipe relining in Sydney is priced per metre of pipe rellined. The cost depends on the pipe diameter, the depth of the pipe, access conditions, and whether additional preparation (jetting, root cutting) is required before liner insertion.
Every job is priced individually after a CCTV inspection. There is a $0 call-out fee, but not on weekends or late night. Call 0426 582 778 for a fixed quote after a CCTV inspection.

Frequently Asked Questions
Pipe Relining Sydney
What is pipe relining and how does it work?
Pipe relining is a trenchless repair method that creates a new pipe inside a damaged existing pipe. Sigma Plumbing inserts a flexible liner saturated with epoxy resin into the damaged pipe, inflates it against the pipe walls, and cures it in place. The cured liner forms a smooth, structural new pipe inside the host pipe, no excavation required. The process complies with AS/NZS 11295 and typically takes one to two days for a standard residential job in Sydney.
Does pipe relining really work?
Yes. Pipe relining is a proven, widely used repair method for damaged sewer and stormwater pipes. When installed correctly to AS/NZS 11295 standards, a cured-in-place pipe liner creates a structurally sound new pipe inside the existing host pipe. Manufacturer-rated liner service life is typically 50 years. Sigma Plumbing provides a post-completion CCTV inspection to verify liner integrity on every job.
How much does pipe relining cost in Sydney?
Sigma Plumbing prices pipe relining in Sydney per job. The final price depends on pipe diameter, depth, access conditions, and how much preparation (CCTV, jetting) is required. Call 0426 582 778 for a fixed quote after an on-site CCTV inspection.
How long does pipe relining last?
A correctly installed cured-in-place pipe liner has a manufacturer-rated service life of typically 50 years. The rellined pipe is resistant to root intrusion (the smooth epoxy surface has no joints for roots to enter), corrosion, and chemical degradation. Sigma Plumbing uses industry-standard liner products and complies with AS/NZS 11295 on every relining job.
Can pipes under a concrete slab be rellined without breaking the slab?
Yes. Pipe relining is specifically suited to pipes that run under concrete slabs, bathroom tiles, driveways, and landscaped areas. The liner is inserted through existing cleanout access points, no need to break the slab or remove tiles. Sigma Plumbing carries out slab-adjacent and under-slab pipe relining regularly across Sydney.
What is the difference between pipe relining and pipe replacement?
Pipe relining inserts a new liner inside the existing damaged pipe, no excavation, minimal disruption. Pipe replacement involves excavating to expose the damaged section, physically removing and replacing the pipe, then reinstating the surface. Relining is preferred when the pipe is under hard surfaces, landscaping, or building structures. Replacement is preferred when the pipe has fully collapsed and the internal diameter is too restricted for liner insertion.
