ABSTRACT:
A method of making a jacketed storage tank comprises applying a layer of wax over a rigid inner storage tank, applying fibrous reinforcing material and resinous material onto the wax, and then curing. The wax is subsequently melted and removed to create a continuous space. 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 is provided by the jacket.
