Flex Wall Drive Over & Through Spill Containment Berm, 12x50x1 ft

The 12x50 Flex Wall is built for full-length tanker truck containment during loading, unloading, and fueling operations. With 5,249 gallons of sump capacity, it handles the volume of a standard fuel delivery truck spill. The 50-foot length accommodates most commercial vehicles without repositioning, while the self-rising end walls keep traffic flowing without manual wall management. The tire track guards included with this berm are critical for high-frequency sites — without them, repeated tire crossings will abrade the berm floor and shorten its service life. The aluminum L-brackets prevent sidewall collapse under wind or incidental contact. If your site handles oversized vehicles or needs additional width clearance, consider the 15x50 model which adds 3 feet of width and 1,796 gallons of additional capacity.
