New application of the calcareous deposit produced by impressed current as cathodic protection in sea water with carried marine sediments. This application will be tested in real situation by producing bonded calcareous deposit with sediment as sand, shell and others minerals carried by waves on the coast. This aggregated material forms a surface with irregular roughness and stop removing sand which causes erosion under structures as rocks barrier building or walls retaining in front of sea or in ports as quay wall. The producer for this material is Geocorail’s equipment which will be deployed along the structure’s bottom.
