A bladder mounting for a storage tank has a plurality of threaded studs, spaced circumferentially along an upper portion of an inner surface of the tank side wall. At least one layer of geotextile padding, is adhered to the inner surface of the wall below the studs. A liner with a reinforced hem has circumferentially spaced apertures which receive the studs and suspend the liner within the tank. A circumferential band of adhesive material along the studs and apertures and between the wall and the liner seals the liner to the inner surface of the tank along a continuous path. A circumferential strip of battan has spaced apertures to receive the studs for clamping the liner against the inner surface of the wall with the band of adhesive therebetween. Nuts and washers engage with the threaded studs and draw the battan toward the wall to secure the seal along the continuous path. At least one relief valve extends through the wall proximate and below the seal and pneumatically communicates from a cavity defined by the wall and the liner to the atmosphere external of the tank. Consequently, as the tank is filled with material to be stored, gases trapped between the wall and the liner and below the seal are released to atmosphere through the relief valve. The seal prevents overflow between the tank wall and the liner and the valve permits the liner to come into abutment with the padding on the tank wall, minimizing the possibility of condensation therebetween.
