Hoover VaulT® Tanks



Containment Solutions, Inc. (CSI) provides safe, affordable solutions for the storage of flammable and combustible liquids. If you are concerned about the effects fuel storage has on your bottom line, look at the advantages of aboveground fire-protected storage tanks.


Our steel Hoover Vault® tanks meet the requirements of all national fire codes for fire-rated aboveground storage tanks and are labeled according to Underwriter’s Laboratories Standard 2085 “Insulated, Protected Secondary Containment”.


Vault tanks utilize patented designs with lightweight fireproofing materials, applied in the interstitial space of UL 142 double-wall tanks. These materials ensure that the inner tank is protected from the effects of fire. This design allows both the inner and the outer tanks to be pressure tested at the factory and in the field. In addition, the fireproofing materials allow liquid to migrate through to the monitoring tube, so leaks from the inner tank are detected. Rectangular vault tanks are space-saving in design.
