It saves the execution of a complete hearth of concrete that is much more expensive and always presents water losses.
The civil work is reduced to a hoop in the perimeter of the deposit.
The optimization of materials means that the best properties of each element component of the deposit are used to their best use, so there are no superfluous elements and this helps a lot when it comes to achieving lower costs (for example, no concrete is made to work to traction).
The sheet allows movements of the ground and seats thanks to its extraordinary elasticity.
The tanks are totally modular, so they can be extended, disassembled, moved, add covers or any accessory without having to modify the previously made.
