Tank Manufacturing Process
You can trust in our tanks for their strength, durability and our meticulous production process.
Each tank is constructed with a single piece design to prevent breakages and leaks within the internal walls. Using specially designed steel moulds ensures consistency in our production.
After every pour, our moulds are carefully inspected, cleaned and prepared for the next use.
To reinforce the concrete, we use 665 steel mesh and extra reinforcement for the lifting points. This internal mesh is centrally positioned to add strength to the structure and meets the requirements of AS/NZS1546.1:2008, ensuring a minimum concrete cover over reinforcement. Although more labour intensive, this ensures a more durable structure than commonly used fibre concrete.
Readymix concrete is poured into the moulds and externally vibrated to ensure all voids are filled and excess air is removed. Once cured, the concrete in our tanks has a strength of 45mpa, twice the strength of a house foundation! After the pour is complete, the moulds are covered and steamed overnight for optimal curing.
Once the concrete is cured, the moulds are rotated, unclamped and lifted off the tank. Our skilled team assembles the required quality components and completes the internal fit out of the system.
We pour the tank lids separately, these are placed on top of the tank bodies and sealed along the joins. A bead of sealant is applied prior to an epoxy mix to minimise the chance of leaking as much as possible.
Before being sent to their new homes, each completed system undergoes a thorough Quality Assurance process.
