Andromède team is dedicated to the study, restoration and valorization of marine ecosystems, with two specialties: posidonia meadows and bio-constructed reefs (coralligenous reefs, coral reefs). Our work and our references are built on three values: - The most advanced methodological approaches and technologies - Intensive sea intervention programs carried out by experienced professionals - Scientific partnerships with academic and university organisations. We intervene with respect and care of our customers and partners, whatever the state of the ecosystem, from exploration to ecological compensation, to integrate each project into its natural and regulatory environment.
