Aussie Trenchless’ flagship – and 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 increased popularity both in Australasia and abroad thanks to its versatility and ease of use.
By installing SRP EXP, asset operators can extend the service life of sewer and stormwater systems by more than 50 years. The product is designed to fit standard size access chambers but is also ideal for tight spaces and locations with bad access.
As the installation process is unaffected by running infiltration and does not need bypass pumping, it is well suited to water applications, particularly as it also enhances the hydraulic characteristics of the rehabilitated asset. The product is available for asset profiles from DN 150 to DN 1200, with such range allowing it to become a standout product to the market.
Aussie Trenchless Director Chris Meredith says he has seen significant growth in the implementation of this trenchless solution all around the world and particularly here in Australia, where it has been implemented in several locations.
A standout product in action
Recently, the spiral lining system was used to rehabilitate corrugated steel stormwater pipes for the Tablelands Regional Council in Queensland at the Ravenshoe Project.
As the pipes – which were each 750 mm in diameter and 33 m long – were in what was described as a ‘horrific’ condition, the contractor decided the only feasible application was Aussie Trenchless’ spiral lining.
With other methodologies, the risk of collapsing the walls could possibly result in a need to dig up the road. As it was the only road providing residents access to their properties, this would have caused major concern and delay with the digging requiring in at least one week of work.
By implementing the Aussie Trenchless solution, the contractors completed a size for size rehabilitation that had minimal risk of collapsing the existing pipe walls. At the conclusion of the project, the contracted engineer was extremely pleased with the final result and signed it off with no hesitation.
Mr Meredith says this project is just one example of how customers are starting to take advantage of the product, with the company receiving lots of market feedback indicating it’s one of the most financially viable and efficient systems available.
“Like all efficient trenchless methods, the spiral lining system helps ensure the works’ aboveground footprint is minimised as much as possible, which includes the land and environment itself, as well as the day-to-day lives of the public in surrounding areas,” says Mr Meredith.
“Other systems need two separate winding machines to install a range of profile to suit pipes from DN 150 to DN 1200. SRP EXP has been designed with one winding machine that installs all sizes of expanding profile for pipes from DN 150 to DN 1200 meaning there is no need for multiple winding machines.”
More than a one-hit wonder
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 by inducing a speedy resign cure during patch and seal lining activities.
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, with operators finding it saves 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.
Both 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.
