Australian Tanks round tanks are a ‘single pour’ tank, constructed with a built-in anti-floatation square base.
Once lowered into the ground, the tank’s weight combined with the back-loaded soil loading on the anti-floatation ‘Wings’ of the base are enough to counter any hydrostatic uplift forces. The Australian Tanks 25kL tank is the only tank that requires an additional 200mm cover to achieve this.
