Expert Insights

At 498 gallons, this 10x20' berm accommodates medium-duty equipment like portable generators, compressors, or single-vehicle maintenance. Copolymer 2000 liner resists a wide range of fuels, oils, acids, and solvents with superior UV stability. Operating range: -40°F to 160°F—suitable for year-round outdoor deployment in extreme climates. Foam walls self-rise in seconds—simply unfold the berm and the closed-cell foam walls pop up automatically with no manual inflation or assembly. The 4-inch wall height provides 498 gallons of sump capacity. EPA 40 CFR 264.175 requires secondary containment to hold 110% of the largest container; verify your stored volume against the 498-gallon rating. Cleaning: Flush with water and mild detergent after spills. Inspect seams quarterly. Patch kits available for field repairs. Store folded when not in use—foam walls retain their shape through repeated fold/unfold cycles.

Frequently Asked Questions

Foam Wall Containment Berm 4"h 10x20' Copolymer-2000

What is the actual sump capacity of the 10x20' foam wall berm?

The inside dimensions are 10 ft x 20 ft with 4-inch foam walls, providing 498 gallons of containment capacity. Under EPA 40 CFR 264.175, this accommodates a single container of up to 452 gallons (110% rule).

How quickly does the foam wall deploy?

Foam walls self-rise in seconds when unfolded—no pumps, no manual inflation. One person can deploy this 10x20' berm in under a minute. The closed-cell foam retains its shape through hundreds of fold/unfold cycles.

What chemicals are compatible with the Copolymer 2000 liner?

Copolymer 2000 is compatible with fuels, oils, hydraulic fluids, acids, and most industrial solvents. It offers the broadest chemical resistance of any berm material we carry.

Can vehicles or equipment drive over the foam walls?

Foam walls are designed for foot traffic and light equipment placement, not drive-over use. The closed-cell foam compresses under heavy loads and may not recover. For drive-in/drive-out applications, consider our collapsible wall or drive-through containment berms.

What is the temperature range for this Copolymer-2000 berm?

Copolymer 2000 operates from -40°F to 160°F, making it suitable for Arctic conditions and hot summer asphalt staging areas.

How do I repair a puncture or seam leak?

Field repair kits are available for both PVC and Copolymer 2000 liners. Clean the area, apply adhesive, and press the patch firmly. For seam failures, contact AbsorbentsOnline—warranty repairs may apply. Regular quarterly inspections catch small issues before they become leaks.

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."
