The hex box was designed to create a breakwater or sill as cheaply
as possible with the least amount of impact on the environment. It
uses a precast concrete structure that can be floated or carried into
position and sunk. The units lock together with their neighbors to
create a massive composite structure to resist the forces of the
waves. It's angled walls with large holes lowers the wave reflection
and allows water and animals to still pass through the structure while
dissipating the wave's energy. This causes the sand carried by the
wave to settle out behind the breakwater, creating a wide beach that
protects the shoreline from storms.
Hex Box:
The map above shows the current installations of Hex breakwaters,
starting in October 2006. As a rule they are about a third of the cost
of an equivalent stone breakwater with a 6 foot height, cover only a
fifth of the bottom and can be installed in days instead of weeks or
months using barges and cranes to move rock. They can also be
relocated easily by re-floating and moving them.
Above is thelay out of a series of Hex boxes, showing how they
interconnect to their neighbors and are secured to the bottom by
concrete pins driven through precast holes in the five inch thick
concrete floors. Pilings are driven in at the ends of the breakwater
to help mark their positions during high tide events.
