Storage tanks having formed jacket for secondary containment

Abstract From the Canadian patent

of Disclosure, A method of making a jacketed storage tank comprises applying a separating agent over the storage tank applying a layer of fibrous, reinforcing material on the separating agent and thereafter, applying a resinous material. The resultant jacket covering at, least about 40% of the surface area of the storage tank is, structurally independent therefrom. True secondary containment can be provided by the jacket. A fail safe containment storage tank system is provided by the use of a leak detection means to monitor the closed space between the storage tank and jacket for tank or jacket leakage.
