Containment That Eliminates Your EPA Exposure

Containment That Eliminates Your EPA Exposure

The $50,000 EPA cleanup bill starts with a missing containment berm. You know the math — 110% secondary containment of the largest container, per EPA SPCC guidelines. The Fol-Da-Dam berm delivers that capacity in a field-proven format. Aluminum L-brackets and a chemical-resistant vinyl liner create a portable basin that handles fuel tanks, frac tanks, totes, and machinery. At Tank Vault, we verify compliance requirements for your state and application before the order ships. You tell us your tank capacity and jurisdiction — we confirm the berm size that satisfies local secondary containment requirements. No guesswork, no inspection failures, no cleanup liability from an undersized containment area.

Portable Containment Without Permanent Install Costs

Portable Containment Without Permanent Install Costs

Permanent concrete containment pads lock your fuel storage into one location. The Fol-Da-Dam berm gives you industrial-grade secondary containment that moves with your operation. Aluminum L-brackets assemble without tools, and the vinyl liner folds flat for transport between job sites. Nine sizes from 6' x 6' to 20' x 50' cover containment needs from 135 to 7,500 gallons. End walls available in 6-inch and 12-inch heights let you match containment depth to your application. For fleet yards, construction sites, and temporary fueling operations, this berm eliminates the cost and timeline of poured-in-place containment — while still meeting the secondary containment requirements your inspector expects to see on walkthrough.

Multi-Application Containment Beyond Fuel Storage

Multi-Application Containment Beyond Fuel Storage

The Fol-Da-Dam berm handles more than fuel tanks. Chemical-resistant vinyl construction makes it suitable for equipment wash-downs, vehicle decontamination, hazmat response, drip pads, and temporary holding of contaminants or sorbents. Overturned truck containment is another field-proven use case — when a spill happens, you need a containment basin that deploys fast and holds until cleanup crews arrive. The collapsible design stores compactly in a truck or trailer, ready for deployment when your operation needs it. For fleet managers and safety officers who need one containment product that covers multiple compliance scenarios, the Fol-Da-Dam replaces single-purpose equipment with a single code-compliant containment asset.

Is This Berm Right for Your Setup?

Confirm your site and containment requirements before ordering. Local municipalities set secondary containment rules — verify your 110% capacity needs with your jurisdiction before purchase.

  • Your primary tank volume requires containment at or below 7,500 gallons
  • Your site has a flat, clear area matching one of the nine available berm footprints
  • Local regulations require secondary containment at 110% of largest container capacity

Common Field Applications

The Fol-Da-Dam berm serves as a multi-purpose containment basin across industrial, municipal, and emergency response operations.

“We use the 12' x 30' Fol-Da-Dam under our 1,000-gallon diesel skid tank at our remote yard. Set it up in under 20 minutes with two guys. Fire marshal signed off on it during our annual inspection — no issues. Beats pouring concrete at a site we might vacate in six months.”

Frequently Asked Questions

Secondary containment requirements vary by jurisdiction. EPA SPCC guidelines typically require 110% containment of the largest container — for example, a 500-gallon tank needs 550 gallons of containment capacity. The Fol-Da-Dam berm is available in sizes up to 7,500 gallons to meet that threshold. However, local municipalities may impose additional requirements. Contact Tank Vault before ordering — we verify your jurisdiction's containment rules and confirm the correct berm size for your tank capacity and site conditions.
Match the berm's containment capacity to 110% of your largest tank's volume. A 500-gallon fuel tank requires at minimum 550 gallons of containment. The Fol-Da-Dam ranges from 135 gallons (6' x 6') to 7,500 gallons (20' x 50'). You also need to account for the tank's footprint — the berm must physically accommodate the tank dimensions. Send us your tank size and capacity, and we'll confirm the correct berm before you order.
Yes. The Fol-Da-Dam liner is constructed from chemical-resistant vinyl, rated for fuel, oil, and chemical contact. The berm is designed for secondary containment of fuel tanks, frac tanks, totes, and chemical containers. It also serves as a hazmat decontamination pool and drip pad for equipment wash-downs. For specific chemical compatibility questions beyond standard fuels, contact Tank Vault with your chemical type and concentration — we'll confirm liner compatibility before your order ships.
Lead times vary by berm size and current inventory. Standard sizes typically ship faster than larger configurations like the 20' x 50'. If you have a site deadline or compliance inspection date, contact Tank Vault before ordering with your required delivery window. We coordinate LTL freight nationwide and can confirm ship dates before you commit. Don't wait until the inspector is scheduled — give us your timeline and we'll confirm whether we can meet it.
Every Fol-Da-Dam berm order from Tank Vault ships with product specifications and capacity documentation. For EPA SPCC compliance, your site plan should reference the berm's containment capacity relative to your tank volume. We include the documentation you need to support your SPCC plan and fire marshal review. If your inspector requires specific manufacturer certification sheets, contact us before ordering — we'll confirm what documentation is available for your selected berm size and ensure it's included with your shipment.
End wall height determines the berm's containment depth and total volume capacity. A 12-inch end wall provides deeper containment and higher gallon capacity than a 6-inch wall in the same footprint. Choose based on your tank height and the gallon volume you need to meet the 110% containment threshold. If you're unsure which end wall height matches your application, send us your tank dimensions and required containment volume — we'll confirm the right configuration.
The Fol-Da-Dam is designed for secondary containment — not as a load-bearing surface. Driving vehicles over the berm can damage the aluminum L-brackets and vinyl liner, compromising containment integrity. For vehicle access, position the berm so vehicles enter and exit over the open side, not across the containment walls. If your application requires drive-through containment, contact Tank Vault — we can discuss alternative containment products designed for traffic loads.
