The Permex is the ideal block for covering artificial reefs or rubble mounds of composite type breakwaters, which has outstanding stability and superior economy. It also contributes to creating habitats for a wide variety of marine life.
- Outstanding stability
Large inside openings and outside notches significantly reduces the up-lift force acting on Permex. Therefore the stability against wave action of Permex can be improved remarkably in comparison with other conventional armor blocks. The Permex is the ideal block for covering artificial reefs or rubble mounds of composite type breakwaters, therefore the 4t type can be used for a wide range of design conditions. - Superior economy
Because high stability of Permex allows to use smaller block, total amount of concrete can be reduced. Therefore Permex has superior economy to those of other conventional blocks. In addition, it is expected such saving of resources will contribute to the preservation of the global environment. - Eco-friendliness
Extremely long ridgelines and five openings of Permex provide a variety of growth environment to marine life.
