A liquid container for the above-ground storage of flammable fuels is shown having an inner tank with a bottom surface, side surfaces, and a top surface placed within an outer shell having a bottom surface, side surfaces and an open top. The bottom surfaces of the inner tank and outer shell are spaced apart from each other, as by first bottom spacers which connect the two bottom surfaces. The side walls of the inner tank and outer shell are also spaced apart from each other, as by second side spacers which connect the tank and shell. The spacers for connecting the tank and shell prevent the inner tank from floating within the outer shell when an insulating material, such as concrete, is added therebetween.

A tank assembly for storing liquids comprising: an inner tank having an interior within which liquids are stored, said inner tank having outer wall surfaces; a liquid absorbing material which will not disintegrate upon contact with liquid contents of the inner tank, said liquid absorbing material disposed about said outer wall surfaces of said inner tank; a sheet-like liquid impervious material surrounding said liquid absorbing material, said sheet-like liquid impervious material defining an envelope surrounding said liquid absorbing material which prevents passage of liquids and moisture across said envelope; an outermost tank surrounding said inner tank, liquid absorbing material and sheet-like liquid impervious material, said outermost tank spaced from said sheet-like liquid impervious material such that a space is defined between said sheet-like liquid impervious material and said outermost tank; and a pourable air-entrapped concrete insulating material disposed in said space defined between said outermost tank and said sheet-like liquid impervious material, said pourable air-entrapped concrete insulating material being cured in situ.
