Expert Insights

The 12x26 Flex Wall is the mid-range option in the drive-over berm lineup, providing 1,203 gallons of containment for medium-scale fueling operations and equipment wash-downs. The self-rising end walls eliminate the setup time required by traditional berms — vehicles simply drive through without stopping to lower and raise walls. The included tire track guards are essential for extending berm life in high-traffic applications; they distribute vehicle weight across the berm floor and prevent punctures from tire treads. The aluminum L-brackets provide rigid sidewall support that maintains the 1-foot wall height even during windy conditions. For sites with frequent vehicle access but moderate spill volumes, the 12x26 strikes the right balance between footprint and capacity. If you need more throughput length, step up to the 12x50 or 15x50 models.

What Our Customers Say

Real reviews from the facilities, field crews, and agencies that count on us.

  • ★★★★★

    "We keep 4-inch quick deploy berms under every piece of heavy equipment on our job sites. When a hydraulic line blows, we can have containment under the machine in seconds. Saved us from two potential EPA violations already this year."

    Mike R.Fleet Maintenance Supervisor / Heavy Construction
  • ★★★★★

    "The 8-inch wall berms with snap-up supports are perfect for our outdoor drum storage area. We went from a non-compliant gravel pad to full SPCC compliance in one afternoon. The galvanized supports keep the walls rigid even in wind."

    Sarah T.EHS Manager / Chemical Distribution
  • ★★★★★

    "Bought the 6-inch folding berms for our maintenance shop. They fold completely flat when we need the floor space for other work, then pop right back up for oil changes and equipment servicing. Great quality — the welded seams don't leak a drop."

    Jason K.Maintenance Shop Supervisor / Manufacturing
