Secondary containment panels and process for making and installing same

Abstract

A method of manufacturing a plurality of secondary containment panels and assembling and installing the panels in a secondary containment system of an above-ground liquid storage tank or other retention facility includes forming a plurality of flexible substrate pieces. A liquid impermeable coating is applied to the upper surface of each piece such that an edge segment of the piece remains uncoated. The coating is applied to the substrate piece in an indoor enclosure. The coated pieces are delivered to the site of the tank and extended across the ground adjacent to the tank. At least a pair of the pieces are juxtaposed relative to one another such that a first one of the pieces overlaps the uncoated segment of the second piece to form a seam. An adhesive substance is then applied to the seam to fasten the first and second pieces together.
