Expert Insights

The 12x25-foot L-Bracket Instant Berm provides 2,244 gallons of containment capacity — meeting the EPA 110% secondary containment rule for equipment displacing up to approximately 2,040 gallons. This makes it ideal for large generator sets, multiple fuel tanks, or transformer installations. At 130 lbs, this berm can be deployed by two workers in under 5 minutes. The L-bracket walls lock into position automatically when the berm is unfolded. No stakes, pumps, or tools are needed. Material: The 36 mil reinforced geomembrane resists petroleum products, diesel, gasoline, hydraulic fluid, and mild solvents. For aggressive chemicals (strong acids, caustics), upgrade to XR-5 or Copolymer-2000 liner berms. Sizing Tip: Sump capacity

Why Instant Containment Berms Matter

EPA SPCC regulations (40 CFR Part 112) require facilities that store, transfer, or process oil and petroleum products to implement secondary containment systems sized to hold 110% of the largest single container’s volume plus accumulated precipitation. The L-Bracket Instant Berm provides rapid-deploy, structurally rigid secondary containment — eliminating the field assembly time, connection failures, and leak-prone seams of multi-piece berm systems. The one-piece design with aluminum L-bracket wall supports unfolds in minutes, delivering immediate SPCC-compliant containment for drums, tanks, generators, transformers, and industrial equipment.

The reinforced geomembrane resists punctures, tears, UV degradation, oils, fuels, solvents, coolants, and mild acids and bases.

What Our Customers Say

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

  • ★★★★★
    “The 12x25 instant berm was deployed in under 15 minutes for our outdoor transformer containment pad. The one-piece design with built-in L-brackets is so much faster than the multi-piece berms we used to wrestle with. Passed our SPCC audit with zero findings. Ordered the ground cover mats to protect the liner on our gravel pad.”
    — Facilities Manager, Power Utility
  • ★★★★★
    “We run a fleet maintenance operation and needed drive-over containment. The instant berm with tire track guards lets our trucks pull in and out without damaging the walls. The 12x50 size handles our entire maintenance bay. Great product and the free shipping saved us hundreds on freight.”
    — Fleet Maintenance Supervisor, Trucking Company
  • ★★★★★
    “Bought three 12x12 instant berms for our generator farm secondary containment. The reinforced geomembrane is much tougher than the PVC berms we had before — no more worrying about punctures on rough concrete. Two years outdoors in full sun and they still look new.”
    — EHS Coordinator, Data Center Operations
