Groundbreaking innovation in reef and coastal protection

We have created the first modular artificial reef that is stable enough to stop storm waves for coastal protection but also provides a complex habitat for marine life and a new foundation for corals to thrive

With your help, we want to provide the coastal communities in Gili Air, Indonesia, with these sustainable alternatives to protect themselves in the face of rising sea levels and increased storms.

The problem

Why do coasts need protection?

The island of Gili Air in Indonesia has historically been protected by coral reefs and seagrass fields but are now seeing their island slowly being eaten away by the ocean. Tragically, this is happening all over the world due to the loss of natural protection, rising sea levels and increased storms:

This is not only a disaster for biodiversity but also for people that depend on these natural resources for income and coastal protection. These vulnerable ecosystems are naturally able to reduce waves up to 90% before reaching the coast, protecting vulnerable coastal communities against flooding and erosion.

With the rapid decline of these natural barriers and the ecosystem services they provide, urgent action is needed today.

Why reefs are important

Coral is a vital necessity for our world

of global marine life support

Coral reefs cover only 0.01% of the ocean floor, but support over 25% of all marine life. The tranquil area behind this living breakwater allows for seagrass beds to develop.

faster CO2 takeup than tropical forest

In addition, seagrass is a vital weapon in our fight against climate change. Seagrasses can take up CO2 from the atmosphere 35 times faster than tropical rainforests.

of global coral reefs lost over last 30 years

Over the past 30 years we have lost over 50% of the worlds coral reefs. At the same time seagrass fields, that form a symbiotic relationship with reefs, are declining globally at a rate of 7% a year.

A double-edged sword

With the help of the local community we can restore the seagrass beds, creating additional protection for the coast and forming an effective natural carbon sink. Over the years, Reefy became a double-edged sword by protecting the coast and storing carbon at the same time!

Our journey so far

First prototypes

We worked a lot on the prototypes of the reefy blocks. Especially we were testing in the Eastern Scheldt Flume at Deltares. The final version for the experiment (on the right) was 3D printed!

Tests in coral reef tank

With these tests in Europes largest coral reef tank we aim find new bio-based materials for coral reef restoration around the world!

Media reach

We have been granted a growing attention from medias over the last years with our project. Let’s make it even more visible!

Vision & Mission

What we stand for


Who we are

We are a social enterprise, committed to nature and our mission, and aiming to establish a self-funding organisation. That way, the most sustainable positive impact can be achieved through the establishment and subsequent nurturing of complete marine ecosystems.

“By restoring natural reef barriers we can keep communities safe in the face of sea level rise whilst maintaining the ecosystem services they rely on.”

Leon Haines

Marine Biologist

“Using nature as an inspiration, we strive towards changing the environmental impact of coastal infrastructure from a negative to a positive.”
