QuaDror design is highly stable meeting the same stability criteria as a solid cube with 20% of the volume when flat packed
Design can withstand high stack loading when it is in a filled or unfilled state and can be stacked up to 50 units high when rotomolded and 6 units high when filled with water
The design can withstand hurricane force winds when filled with water with no additional supports
An innovative system has been proposed for assembly which meets engineering requirements and would be cost effective and flexible to implement
Known material grade for the structure has been selected which again is cost effective low density and meets environmental requirements
Mass of the rotomolded empty units is below 25kg meeting international requirements for safe handling by a single person so ensures easy of installation
