Secondary Containment Systems

Job Description: This contract involved four tank farms in coastal Alaska. Each battery contains nume-rous tanks and piping for a variety of fuels. All floors and walls are concrete. All floors and walls received 100 mils POLYSHIELD SS-100® over Amoco #4599 geotextile fabric.

The perimeter of tanks were abraded, primed and masked to approximately 1' above the floor. The geotextile was used to counter-flash over the tank chines as an expansion joint. The POLYSHIELD SS-100® was then sprayed up to the masked line on the tanks, forming a seamless liner. The owner is pleased with the application and has awarded the contractor 14 additional similar tank farms, to be completed in 1997.

Other Coatings Evaluated for Project: Quote - Petro Marine Project Manager, "After looking for several years into liners for tank farms, we have found this to be the best liner system on the market today. It has the advantages of not having to have sand over the top, which will give us 100% monitoring ability daily and the ability to clean up any fuels without contaminating the ground cover over a buried liner. The second reason this liner is superior is that we can visually examine the integrity of the liner at any time. There isn't a buried liner anywhere that can be examined or determined to be leak tight. In most cases on seamed, roll liners, the seams start coming apart within a couple of years."
