Expert Insights
The 12-inch manually-collapsible walls fold flat for vehicle and equipment access, then lock upright for containment. Unlike foam walls, these rigid walls provide a full 12 inches of containment height—significantly more sump capacity per square foot. Walls are manually raised and secured with built-in support brackets.
Copolymer 2000 liner provides the broadest chemical resistance available: fuels, oils, hydraulic fluids, acids, solvents, and most industrial chemicals. Operating range: -25°F to 160°F for year-round outdoor deployment.
EPA 40 CFR 264.175 requires secondary containment at 110% of the largest container. This 5610-gallon berm accommodates containers up to 5100 gallons. The collapsible wall design allows equipment to be rolled or driven in with walls down, then walls raised for containment during operation.
Maintenance: Inspect seams and wall hinges quarterly. Flush with water and mild detergent after spills. Check wall support brackets for secure locking. Patch kits available for Copolymer 2000 field repairs.
Frequently Asked Questions
What is the sump capacity of the 15x50' manual collapsible wall berm?
With 12-inch walls and inside dimensions of 15 ft x 50 ft, this berm holds 5610 gallons. Under EPA 40 CFR 264.175 (110% rule), it provides secondary containment for a single container up to 5100 gallons.
Can vehicles drive into this berm?
Yes—fold the walls flat, drive or roll equipment in, then manually raise the walls and lock them into position with the built-in support brackets. This is the key advantage over foam wall berms, which cannot support drive-over traffic.
How do the collapsible walls work?
Each wall section hinges at the base and folds completely flat against the liner floor. To deploy, manually lift each wall section to vertical and engage the locking support brackets. One person can set up most sizes in 5-10 minutes.
What chemicals is the Copolymer 2000 liner compatible with?
Copolymer 2000 handles fuels, oils, hydraulic fluids, acids, solvents, and most industrial chemicals. It offers the broadest chemical compatibility of any berm material, with superior UV resistance for long-term outdoor deployment.
What temperature range can this berm handle?
Copolymer 2000 operates from -40°F to 160°F—suitable for Arctic conditions through hot summer deployments. The material remains flexible and functional across this entire range.
How do I repair damage to the liner or walls?
Field repair kits are available for Copolymer 2000. Clean the damaged area, apply the adhesive, and press the patch firmly. For structural damage to wall hinges or support brackets, contact AbsorbentsOnline for warranty evaluation and replacement parts.
How does the collapsible wall mechanism work?
PVC sidewall supports hold the 12-inch walls upright. Swivel the "feet" of the supports to lower or raise a sidewall in seconds for easy access, then raise it again.
What is the collapsible wall berm used for?
Spill containment for large quantities of drums, vehicles, frac tanks and other large containers. An optional self-bailer drains rainwater and shuts off automatically if there is a spill.
