Cubipod is much more hydraulically stable than any other massive pieces on the market, with values of KD (the Hudson formula stability coefficient) much higher than the most frequently used massive pieces, such as conventional cubic blocks or Antifer blocks.
Their hydraulic stability is similar to bulky units (which withstand wave action mainly by interlocking), but they behave in a more flexible way and have a gravity and lateral-friction based strength mechanism.
The hydraulic stability of Cubipod has been tested in many European port engineering test laboratories (Read more… (takes the reader to the Laboratory Test section)), resulting in the following stability coefficients (KD) being adopted:
Trunk: KD = 28
Round-head: KD = 7
Trunk: KD = 12
Round-head: KD = 5

It is recommended that main armor units are constructed with 3/2 slopes, because this is cheaper and there is less environmental impact. However, as they are massive pieces and the weight of the blocks withstands wave-generated forces, Cubipod can be placed on gentler slopes to adapt to the requirements of each project.
