GEOCORAIL installs a test rig in the Fos oil port

Man is just as determined to destroy as to build.

Geocorail protects the seascape by reconstituting a natural rock that fights erosion while trapping carbon and some heavy metals.

Geocorail® is manufactured in situ using a combination of electrochemical reactions in seawater and sediment collection.

This device enables the formation of a rocky conglomerate around a grid specially designed to receive the aggregates.
The aggregation process uses very low-intensity electric currents circulating in seawater and in the soil and sediment or debris carried by the waves.
