ABSTRACT:
A method of making a storage tank comprises applying ribs around a inner tank, securing said ribs to the inner tank, applying gas pervious material in the space between the ribs, and applying a layer of fibrous reinforcing material and resinous material over the gas pervious material. The gas pervious material extends to a distance less than about 75% of the height of the ribs. The resultant overlay encases the surface areas between the ribs of the storage tank, and becomes a structural part thereof. Secondary containment is provided by the overlay. A monitored storage tank system is provided by the use of a leak detection means to monitor the closed space defined by the rib interiors the overlay and the storage tank.
