A method of making a jacketed storage tank comprises applying an open-cell synthetic foam over a rigid inner storage tank, applying a layer of fibrous reinforcing material on the separating agent, and applying a resinous material. The synthetic foam is at least partly sealed to prevent excessive resinous material penetration so as to maintain the continuous open-cell nature of the foam. The resultant jacket is structurally independent from the storage tank, yet is in such close proximity thereto that the resultant jacketed storage tank has an integral structural strength capable of withstanding external load forces normally encountered by underground storage tanks. Secondary containment with leak detection capability is provided.

A storage tank for liquids having secondary containment capability and sufficient integral structural strength to withstand external load forces normally encountered by underground storage tanks, comprising: (a) a rigid inner tank for storing the liquid; (b) an open-cell synthetic foam as a separating agent on an outside surface of the inner tank, said foam characterized in having its outside surface at least partly sealed to retard penetration of liquid resinous material; and (c) a jacket made of a fibrous reinforced resinous material which completely covers the storage tank to form a closed space, said packet characterized in having resin support column extending from its underside, further wherein said jacket is structurally independent from the rigid inner tank because of the separating agent, yet is in close proximity to the storage tank so that said jacket and inner tank reinforce one another to achieve the integral structural strength.
