ABSTRACT:
A method of forming a storage tank from an existing matrix tank comprises adding spaced internal support ribs. The interior surface of the matrix tank is covered with a layer of fibrous reinforced resinous material to form a main body and internal support ribs are added. The main body and support ribs are secured together such that the ribs protrude inwardly. The formed tank is fully and independently capable of containing liquid and withstanding normal internal and external load forces. A double walled formed storage tank system is also provided wherein an inner wall between or on the internal support ribs is added.
