Zerion FVS has been used in multiple tank soil side bottom installations. It provides superior protection to exposed steel in vapor spaces and crevices under the tank bottoms and in situations when there is ingress of water into the tank foundation space. FVS can be diluted with water and injected into sand/soil base or introduced as a powder during tank construction or bottom plate refurbishment. Even for tanks with concrete pad foundations, FVS in slurry form can be introduced into the spaces between the plates and the concrete to provide corrosion protection. Zerust has also pioneered a VCI Ring system using FVS if there is no liquid injection. This VCI Ring system is recommended for all SSB installations.
