Bio-Active Concrete Solutions - Re-establish damaged marine ecosystems and improve marine biodiversity restoration

The marine biodiversity is under big threat: more than half of corals reefs and seagrass have disappeared since the 20th century and over 40% of the ocean surface shows critical signs. Experts estimate that 1/8 of marine species could have disappeared by 2050 if no action is taken. This solution aims to restore marine biodiversity. By boosting the natural process of habitats decolonisation, it enables marine life to come back. There are many reasons for which marine restoration is urgently needed: boost the coral's colonisation in the environments stressed by climate change or fight against installation and spread of invasive species, ... On top of these rationales, the main benefit of emerging a reef is to support coastal fishing by targeting specific types of fishes and/or to promote the tourism.

Key features

  • Mechanical strength - 70MPa (without steel rebars)
  • Durability in marine/river environment (50 years of service life) and low pH
  • Bio-Active Concrete is more efficient than an ordinary concrete, with a kinetic of algae growth 4 times faster and with almost 5 times more covered surfaces.
  • Bioactive concrete reduces impacts across almost all the impact & resource use categories, with a reduction in GWP reaching 41% compared with traditional concrete
  • Taking into account the colonization results, the good colonisation potential of the bioactive concrete could lead to over 5 times higher GWP savings compared with traditional concrete


  • Job creation : tourism increase by creation of resorts with specific diving spots
  • Price of these green infrastructures balances the penalties that Authorities (national/local ones) would pay for marine biodiversity destruction.
  • Positive impact on fishery industry as the solution can attract specific species against invasive ones
