Protection from coastal erosion and enhancement of marine ecosystems

Page last modified
March 14 2023

Reef Enhancing Breakwaters (REB) are modular artificial reef structures. REB is stable to dissipate wave energy to protect the coasts from erosion whilst providing the required substrate and habitat complexity to boost marine biodiversity.

REB is a unique solution distinctly different from traditional breakwaters and artificial reefs. Traditional solid concrete breakwaters can be damaging to marine ecosystems, while currently available artificial reef structures are often not stable enough to dissipate waves and ensure coastal protection.

About Reefy

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.
