ABSTRACT:
A reservoir containing layered liquids is lined with a liner comprising a reaction resistant material lining the portion of the reservoir in contact with a reactive liquid with the remainder of the reservoir lined with a material that is not resistant to reaction with the reactive liquid. In a specific embodiment asphalt impregnated nonwoven fabric is used to line a reservoir portion in contact with water and butyl rubber impregnated nonwoven fabric is used to line the portion of the reservoir in contact with a hydrocarbon liquid floating on top of the water layer. In a specific embodiment sheets of liner material are fastened together in a liquid proof seal produced by facing liner sheets to be joined together, overlapping the face sheets with a layer of nonwoven fabric, sewing through the four strata laminate thus produced, and treating the nonwoven fabric with a liquid proofing substance.
