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.

A double walled storage tank system having two closely associated discreet walls held together in a manner which creates a closed communication space, said storage tank system comprising: (a) a tank; (b) an overlying continuous wall of a resinous material closely associated with at least a portion of the tank; and (c) an array of interlocking filament bundles disposed between the tank and the overlying continuous wall, whereby a first face of the array is bonded to the tank, a second face of the array is bonded to the continuous wall and a mid-portion of the array is in a substantially unbonded state to provide a closed communication space for the detection of any leakage through a wall, wherein the bonding of the array of interlocking filament bundles to the walls and the inherent strength of the array of interlocking filament bundles hold the tank wall and the continuous wall together.
