SRP modules have been initially designed in 2016 to increase the natural resiliency of coral reefs surounding Pangatalan Island (Philippines).
The primary objective was to help regain the natural reef cohesion and structural strenght that were lost. SRP provides new habitat for marine flora and fauna.

composition of SRP reef, 56 coral cuttings possible.






Fish eating coral

They are made of reinforced concrete and Contain no plastic or chemicals, the manufacturing is In-situ. SRP assure a permanent coral growth for unstable fragments, support all types of coral morphology and allows natural coral, sessile fauna and flora recruitment. First results in Pangatalan Island show 90% survival rate and 70% of self attached fragments after six months.

Coral cutting


Ecosystem restoration is not an easy task, either on land or underwater. Many innovative methods have been developed but success reside in global vision and strategy for the restored site, so we go trough different steps before installing the SRP. A survey and expertise of the site must be done to evaluate the needs and impacts. This step allow us to work on impacts reduction and choose the right sites for implementation. Finally, Coral Reef Restoration can be practiced. An evaluation should follow.

evaluations and observations of the impacted areas

In order to determine best site for the SRP restoration, we conduct surveys using photo quadrats-transect and ecosystems mapping. We also map the impacts as well as their intensity. Those evaluation and observations give us a good understanding of the impacted areas and how to act to improve the resiliency.Sustainability and Governance are a key factor for ecosystems integrity improvement. We spend time understanding and improving the governance of the sites. Our governance concept is based on 3 points :
– Knowledge and understanding of site
– Local Population
– Ecosystems and Resources preservation

monitoring of coral growth

After reducing as much as we can the impacts on the reefs,
we install our SRP. We compose groups of SRP with different
sizes in order to create structural complexity. We can also adapt
the module to be stable in steep slopes. As the SRP can support
the growth of all types of corals, we fix the fragments at different
places depending of their species and morphology.

Composition SRP on site

After developing the method in Pangatalan Island we wish to spread the innovation to others places. New implementation sites are soon to be open in Singapore and Malaysia. We are creating an online database to show and share our data, results and projects with our partners and members (developing phase).
