ABSTRACT:
A double walled storage tank system has two closely associated discreet walls with a closed communication space therebetween. The system comprises (a) a tank having a main body side wall and attached end walls, (b) a continuous wall of a fibrous reinforced resinous material which substantially follows the contour of at least a portion of the tank and (c) an array of interlocking filament bundles disposed between the tank and the continuous wall. The array has a first face bonded to a tank wall and a second face bonded to the continuous wall. A mid-portion of the array is in a substantially unbonded state to create the closed communication space for leak detection purposes. The strength of the double walled storage tank system is substantially enhanced by the array securely bonded to both the tank wall and the continuous wall and by its own inherent tensile strength.
