The NorthConnex project in northern Sydney is a $3 billion project that will connect the M1 Pacific Motorway at Wahroonga to the M2 Motorway at West Pennant Hills via a nine-kilometre tunnel. The tunnel is set to open in 2020 and will remove up to 5,000 trucks off Pennant Hills Road each day, and help reduce travel time by approximately 15 minutes.
The contractors for the NorthConnex project required conical mixing tanks for mixing concrete admixtures onsite. The solution needed to provide mobility and flexibility for set up of the mixing tanks and their use. As the project is short-term (approximately 5 years), they were looking for a complete package that would be easy to repurpose, including transportable tanks and agitators engineered to their specifications. The erosive nature of admixtures along with Australia's harsh weather means non-corrosive materials with high UV stabilisation are important to use.
Discussions between the project contracting team and the Polymaster team came up with the solution of 3 X 10,000L non-corrosive polyethylene conical tanks, with stainless steel frames and agitators. The agitators are also stainless steel, engineered to the client's specifications, and the tanks include internal baffles to facilitate the mixing system. Extra pipework was also installed to the tanks to make filling and emptying easier. This engineered solution provided the ultimate system for the particular project parameters and requirements.
