What Is UV Pipe Relining?
UV pipe relining is a trenchless pipe repair method that uses ultraviolet light to cure a resin-saturated liner inside your existing pipe. Unlike conventional relining methods that rely on steam heat or ambient air curing, UV curing is faster, more controlled, and produces a harder, more durable result.
The outcome is a fully structural pipe within a pipe, sealed from the inside, with no excavation of your garden, driveway or flooring required.
If you are dealing with a cracked, broken or root-damaged pipe, UV relining is one of the most efficient long-term solutions available today.
How UV Pipe Relining Works
UV pipe relining follows a precise five-step process from inspection to completion.
Step 1: Before any work begins, our team runs a CCTV drain inspection through your pipe to assess the damage, confirm pipe dimensions and identify any blockages or debris that need to be cleared first.
Step 2: The pipe is thoroughly cleaned using high-pressure water jetting to remove buildup, scale or root matter. A clean surface is essential for the liner to bond correctly.
Step 3:Â A fibreglass-reinforced liner saturated with UV-sensitive resin is inserted into the damaged section of pipe and inflated to press firmly against the pipe walls.
Step 4: A UV light train is pulled through the liner at a controlled speed. The UV light triggers the resin to cure rapidly from the inside out, creating a hard, jointless pipe within the original host pipe.
Step 5: A CCTV camera is run through the newly lined pipe to confirm a full, even cure with no voids or defects before the job is signed off.
UV Pipe Relining vs Traditional Pipe Relining
UV relining and conventional steam or ambient-cured CIPP (cured-in-place pipe) relining are both no-dig methods. The key differences come down to speed, precision and liner performance.
| Â | UV Pipe Relining | Traditional CIPP Relining |
|---|---|---|
| Cure time | Minutes | Hours |
| Curing method | Ultraviolet light | Steam heat or ambient air |
| Liner material | Fibreglass-reinforced | Felt or fibreglass |
| Precision | Controlled by UV light speed | Variable depending on conditions |
| Suitable pipe sizes | DN100 to DN600 | DN100 to DN600 |
| Lifespan | 50+ years | 50+ years |
Both methods avoid excavation and deliver a structurally sound pipe. UV relining is particularly well-suited to situations where fast cure times matter, or where site conditions make long ambient curing periods impractical.

What Can UV Pipe Relining Repair?
UV pipe relining can address a wide range of pipe damage in residential and commercial properties:
- Cracked or fractured pipes caused by ground movement, age or pressure
- Tree root intrusion where roots have entered pipe joints or fractures. For severe root damage, see our tree root removal service
- Leaking pipe joints where sections have separated or corroded at connection points
- Partially collapsed pipes where the pipe has deformed but not fully failed
- Corrosion damage in older clay, cast iron or concrete pipes
- Recurring blocked drains caused by structural pipe defects rather than simple blockages
UV relining addresses the underlying structural issue rather than treating the symptom. If your pipes keep blocking or leaking, the cause is often damage that only relining can permanently fix.
Benefits of UV Pipe Relining
- Fast cure time – UV curing takes minutes rather than hours, getting your drains back in service sooner
- No excavation required – no damage to your garden, driveway, concrete or flooring
- 50-year liner lifespan – the cured liner is rated to outlast most original host pipes
- 25-year installation guarantee – backed by annual camera inspections
- Root penetration prevention – the jointless liner removes the entry points roots exploit
- AS3500 compliant – Curran uses only watermarked liners that meet Australian standards
- Upfront pricing – full quote before work starts, no surprises
- Permanent repair – not a patch, not a temporary fix
Frequently Asked Questions
UV cured liners have a 50-year design life. Curran backs every installation with a 25-year guarantee and annual camera inspections to keep your pipes in good condition.
Cost depends on pipe diameter, the length of pipe being lined and access conditions. The most accurate way to get a price is to book a CCTV inspection so we can assess the job properly. We provide a full written quote before any work starts.
Most residential UV pipe relining jobs are completed in a single day. The UV curing stage takes minutes per metre of liner, which makes it significantly faster than steam-cured alternatives.
UV pipe relining is compatible with clay, concrete, cast iron, PVC and HDPE pipes. It suits sewer, stormwater and drainage pipes in the DN100 to DN600 diameter range.
Standard residential pipe relining does not typically require council approval. Our licensed plumbers handle all compliance requirements and will advise you if your specific job has any additional considerations.
