Impressed with the use of AFS Rediwall at their hilltop mansion, the owner of Jamberoo Action Park in NSW decided to use the permanent PVC formwork system in the build of the theme park’s latest water attraction.

Nestled between the mountains and the sea, just an hour south of Sydney, Jamberoo Action Park is NSW’s largest family-owned and operated water theme park. In 2019 the park lodged a development application for the construction of a spectacular new ‘high adrenaline’ dual waterslide, Velocity Falls.

Designed by Queensland architect Alan Griffith, the multimillion dollar project is described as an eight-lane ‘Octokraken Racer’, with an overall ride length of around 160 metres and an elevational drop of 21.59 metres.

“The Falls also incorporates an additional two ‘multibump speed slides’, which take off from a ‘Skybox vertical launch’ platform, through the gorge rock strata to the splashdown on each side of the Octokraken Racer” Griffith said.

Proven structural technology

When it comes to the construction of the biggest and best water ride of its kind in the world, you want to make sure you’re using the best technologies and methodologies to build it. After having witnessed first-hand the strength, versatility and installation speed of AFS Rediwall in his own home build, the action park owner didn’t take much convincing to use the formwork system extensively throughout the Velocity Falls development.

Builder Jason Van Overmier of Urban Style Building Services explained how Rediwall came to be used in both projects.

“I showed him the AFS product and what I’d done previously with it, and he was really happy to use that on his [home build] project and he was so happy with the speed and the ability to get the product up and make it work for all different areas, so we decided to integrate it into the construction here [at Velocity Falls].”

Construction started during the Covid and severe weather event years of 2020 and 2021, with delays and postponements needing to be factored into the building schedule.

The Urban Style Building Services team led by Jason installed AFS Rediwall throughout the project.

AFS Rediwall – Trusted for mission critical applications

“We’ve used it on the pump house, which houses six pumps, which pump all the water back up to the tower, which is also constructed with the AFS Rediwall product.”

“And then we’ve also built a 450,000-litre capacity water tank, which will then carry all the water flow from the waterfall and then down to this pump room and then get returned back up to the tower.” With Jason’s experience using AFS Rediwall in other challenging projects, he is familiar with its strong performance and is confident in the system’s capability.

Being a loadbearing structural walling solution, AFS Rediwall is also used in other mission-critical applications throughout the site.

“We are using it on pedestal retaining walls, which will actually support the water slide. And we’ve also got a couple of tunnels that we need to manufacture as well out of AFS for the toboggan tracks.”

To embed the slide and its water carrying structures into the hill, extensive excavation and tunnelling work was required, and so it was important to be able to install the retaining walling quickly and safely to avoid the potential of earthen banks collapsing. Jason compared the choice of AFS Rediwall to conventional blockwork.

“In terms of speed and getting walls up in areas where you may have an issue with water seepage or earth banks collapsing, we can have the product installed a lot quicker, get them poured in a timely manner.”

AFS Rediwall benefits continue to impress

Jason went on to commend Rediwall for its clean worksite benefits.

“It’s a good product and we’re happy to use it everywhere we can by eliminating the issues of having a wet trade on site – block layers, brick layers.”

Customer support from the local CSR product team is also highly valued by the Urban Style Building Services crew.

“Never had any issues with getting materials on site. Always had a good relationship with the project managers and supplier in that regard and get along well with them. It makes our job a lot easier.”

The new attraction is due to be in action for the summer of 2022.
