The Seaboost 3D printed mega reef structure has reached its final destination. The 105-ton module was immersed at a depth of 20 meters off the Island of Brescou, at Cap d’Agde (France), in the local Protected Marine Area (Mediterranean Sea).

The Mayor of the City of Agde Gilles d’Ettore and the Director of the Marine Environment Renaud Dupuy de la Grandrive recalled the project’s originality, which is an international first. This 3D printed mega reef is intended to help manage the pressure of anchored boats and diving activity on fragile natural sites. In a few days, the first divers will be able to explore this unique underwater structure.

In April 2022, the 3rd stage of the pressure offset reef for divers was put in place. On the port of the Occitanie/Pyrenees-Mediterranean Region of Sète Frontignan, the dome built with 3D low-carbon concrete walls was installed to complete the structure.

After 3 years of high-level technological and ecological engineering work piloted by Seaboost Ecological Engineering, in collaboration in particular with Centrale Marseille, and the work of expert construction 3D printing companies such as XtreeE, CyBe Construction, Beton Vicat Ciment Calcia Superbloc Pascal Matériaux from Montpellier, Rufino Construction.

This central module measuring 6.50 meters in height on an 8 x 6-meter base, will join an “artificial reef village” with small tower modules, ragues, clusters and riprap over a 50-meter stretch, on the seabed off the Island of Brescou.

The concrete structure was built by XtreeE and Cybe As a pressure offset for diving activities, it will serve to protect sensitive natural coralligenous sites towards this dedicated site. The project was widely shared with diving clubs and maritime stakeholders. It is part of the Reciflab program labeled at the national level and implemented by the marine environment department of the city of Agde. It is funded by ADEME (Ministry of Ecological Transition), the Occitanie/Pyrénées-Méditerranée Region and the city of Agde.
