Winding up the competition

Aussie Trenchless maintains its position as an industry pioneer with a penchant for the unique and innovative.

Aussie Trenchless’ most popular product is a close fitting structural spiral ribbed PVC trenchless pipe lining system known as the SRP EXP. Used for circular sewer and storm water gravity mains, the method has seen an increase in popularity around the world thanks to its versatility and ease of use.

SRP EXP can be fitted to both standard size access chambers as well as tight spaces with difficult access, with the product available for asset profiles from DN 150 to DN 1200. It enhances the hydraulic characteristics of the rehabilitated asset, making it particularly well suited to water applications, while the installation process is unaffected by running infiltration and does not need bypass pumping.

Aussie Trenchless continues to make inroads throughout the world with its spiral winding system, with a customer in Asia purchasing a set of the equipment and profile in 2019. The winding equipment was vigorously tested by the experienced contractor who had previous experience with a different spiral system.

The SRP EXP profile and equipment performed extremely well and met all expectations as it held up against some tough treatment from local technicians. Aussie Trenchless Director Chris Meredith says this marked the first time wastewater pipes in Asia had been lined with the SRP EXP system.

“I expect to see a steady stream of SRP EXP profiles being exported into Asia throughout 2020 and beyond,” he says. “I’ve had a number of enquiries in this region about my profile and equipment and do expect this area to be an important part of the company’s future growth. I also expect to be sending more profile to the Americas soon and I really value Aussie Trenchless’ repeat customers.”

More in the arsenal

While the SRP EXE is at the forefront of Aussie Trenchless’ offerings to the market, the company’s Hot Sleeve Jacket is a product that remains popular among customers. The Hot Sleeve is a tight-fitting heating jacket that is secured over a patch inflatable packer to reduce ambient cure period without reducing its life.

Used by Aussie Trenchless customers to induce a speedy resin cure during patch and seal lining activities, operators are finding that using Hot Sleeve can save up to 60 per cent in crew times.

Aussie Trenchless has also caught the industry’s attention with its Pipe Segment Technology (PST) – a man entry lining system using transparent polypropylene lining panels for the rehabilitation of gravity sewer mains. Easy to build and fast to implement, PST lining panels are made of polypropylene material which provides a smooth surface with excellent hydraulic performance characteristics.
