A storage tank system has two closely associated discreet walls with closed communication flow paths therebetween. The system comprises (a) a tank having a main body side wall and attached end walls and (b) a composite wall which substantially follows the contour of at least a portion of the tank. The composite wall includes a base layer of filament bundles. The base layer is bonded to a tank wall by a resinous material and is covered by additional resinous material. A mid-portion of the filament bundles found in the base layer is in a substantially unbonded state to create the closed communication flow paths for leak detection purposes. The strength of the storage tank system is substantially enhanced by the composite wall.

[ What is claimed is:] [1.] A storage tank system having a closed communication space between two closely associated discreet walls, said storage tank system comprising:(a) a storage tank having a main body side wall and attached end walls at each end thereof; and(b) an overlying composite wall of (1) a resinous material and (2) a base layer of discreet filament bundles running generally in one direction whereby the resinous material encompasses the base layer of discreet filament bundles and at least partially penetrate between individual bundles while a mid-portion of each said filament bundle is substantially resin-free to provide flow paths for the detection of leakage.
