Protection from coastal erosion and enhancement of marine ecosystems

Page last modified
August 28 2024

The Reefblock is a modular reef structure that can be used to form breakwaters, dams or as add-onn in scour protection. The unique hydrodynamic design tested at Delters dissipates wave energy while at the same time providing a underwater habitat for biodiversity.  The Reefblock is unique in its design, being developed with the aim of promoting biodiversity and stability from the start. 

 

Where traditional solid concrete or rock breakwaters can be damaging to marine ecosystems, reflecting waves and providing litte complex habitat. Artificial reefs are often not stable enough to perform coastal protection functions. Reefy solves both these problems with the Reefblock.

 

The solution has been piloted in the Netherlands on full scale, and is ready for full scale application in Europe and Mexico

Reefy has developed and tested the first modular artificial reef structure that is stable enough to dissipate wave energy to protect the coasts from erosion whilst providing the required substrate and habitat complexity to boost marine biodiversity. This patented innovation in coastal infrastructure is the REB: Reef Enhancing Breakwater.

Natural coral reefs are supporting 25% of marine life globally, however according to the latest estimates 70-90% of reefs may disappear due to global warming. Reefy's solutions combine marine biology with engineering to protect livelihoods and food supply of one billion people in the coastal areas.
