A composite storage tank is built which has double wall characteristics. A method of building the tank comprises the steps of applying a viscous resinous core material to a support surface and then winding onto, into or along with the viscous resinous core material discrete filament bundles. The resinous core material encapsulates the filament bundles, but does not significantly penetrate into an interior of the bundles. The substantially resin-free interiors provide flow paths for the ready detection of wall leakage. The resultant composite storage tank has double wall characteristics. A crack or hole in either an inside or outside surface which extends at least to the encapsulated filament bundle interiors will alert the tank's operator/owner to a leakage problem.

[ I claim:] [1.] A method of building a composite storage tank having double wall characteristics, comprising the steps of:(a) applying a viscous resinous core material to a support surface;(b) winding onto, into or with the viscous resinous core material discrete filament bundles so as to encapsulate said filament bundles, yet not significantly penetrate into said filament bundles; and(c) at least partially curing the viscous resinous core material to form a cylindrical-shaped tank wall whereby an interior of each said filament bundle is substantially resin-free to provide continuous closed communication flow paths which allow detection of leakage in said tank wall.
