Trelleborg DrainPacker: The Smarter Way to Repair Pipes — No Digging Required
As Australian infrastructure continues to age, the need for efficient, non-invasive pipe repair solutions has never been more urgent. That’s where Trelleborg’s DrainPacker system comes in — a reliable, trenchless pipe rehabilitation method designed to restore damaged sections of sewer and stormwater pipelines without excavation.
Whether you’re a plumber, contractor, or council asset manager, this system makes sectional pipe repair simple, cost-effective, and compliant with Australian regulations.
What Is the DrainPacker System?
The Trelleborg DrainPacker is a short-liner method used to repair localised damage inside gravity pipelines — typically for pipe diameters ranging from DN 100 to DN 600 (with options up to DN 1200). It uses an inflatable packer and a glass-fibre mat saturated with silicate resin to create a structural, watertight lining inside the pipe.
Benefits for the Australian Market
- Trenchless technology – No need to dig up roads, driveways or landscaped areas
- Fast curing – Silicate resins cure within 1–3 hours at ambient Australian temperatures, even in wet or partially flowing pipes
- Durable – Independently tested to last over 50 years, with many installations rated for up to 100 years
- Environmentally safer – Resins are styrene-free, low VOC, and suitable for potable water systems in accordance with AS/NZS standards
- MRWA Compliant – Systems and materials are recognised by the Major Roads Water Authority (MRWA) in Victoria and compliant with WSAA codes
Ideal Applications
- Cracked or corroded pipes
- Joint displacement or leaking connections
- Root intrusion points
- Patch repairs for stormwater and sewer networks
- Closing unused laterals
- Under roads, buildings, carparks or landscaped areas
How It Works
- Prepare the Pipe – Use high-pressure water jetting and CCTV inspection to locate and clean the area needing repair.
- Fill the Mat – A glass-fibre mat is saturated with silicate resin and wrapped around an inflatable packer.
- Position & Inflate – The packer is positioned at the defect site and inflated to press the mat against the pipe wall.
- Cure & Remove – Once cured (usually in 60–180 minutes), the packer is deflated and removed, leaving a smooth, sealed internal liner.
Certified Quality
