Flex Wall Drive Over & Through Secondary Spill Containment Berm

Flex Wall Drive Over & Through Secondary Spill Containment Berms are engineered for active drive-through operations where vehicles need to enter and exit the containment zone without obstruction. Featuring self-rising flexible wall ends and aluminum L-brackets for dependable sidewall support, these berms maintain a stable 1-foot wall height while allowing unrestricted vehicle access. Yellow tire track guards protect the drive-path liner from wear, and the heavy-duty construction delivers sump capacities ranging from approximately 1,200 to over 4,600 gallons depending on the size selected. Available in configurations from 12×26 ft. up to 15×50 ft., these berms are manufactured by Berg — a specialist in drive-through containment engineering.

Uses: Fleet maintenance bays, vehicle fueling stations, equipment service areas, truck wash pads, and any facility requiring EPA 40 CFR 112.7 and SPCC-compliant secondary spill containment with uninterrupted drive-through access. Ideal for operations where stopping to remove or reposition containment walls is impractical or creates safety hazards.
