Fishes Swarm around the Reef

7 years after installation – Ehime Pref., Japan
  • Sea water stream from openings whirls up within the block, curling up nutrient on the sea bed, for which plankton and fishes swarm around.
  • Spacious walls and bottom help undersea lives stay attached to the reef, which attracts fishes living around the sea bed.
  • Due to its low gravity center, the reef delivers excellent stability while working and after installation.
  • Fewer number of formwork parts makes it easy to put them together, and to dismantle them.
  • The concrete reefs can be casted on site using steel formworks.
