Questions and answers

How much does the Self-Rising Wall Containment Berm hold?

Up to 2,333 gallons, with 12 in. walls.

How do I size a containment berm?

Find the largest tank, tote or vehicle compartment that will sit in the berm. SPCC rules require the berm to hold that full volume plus room for rain, and a common rule of thumb is at least 110% of the largest container. Pick a berm whose capacity meets that number.

Can vehicles drive into it?

Yes. The walls lie flat when the berm is dry, so vehicles drive over them; they rise on their own when liquid flows in.

What liquids can it hold?

Copolymer-2000 stands up to fuels, oils, solvents and many aggressive chemicals. For strong acids or unusual chemicals, call (800) 869-9633 and we will confirm compatibility.

What about rainwater in the berm?

Rain collects in an outdoor berm and uses up capacity, so check it after storms and remove clean water. A berm bailer or drain lets you remove water in a controlled way; never drain water that has a sheen.

Do I need a ground mat?

A ground mat or tarp under the berm protects the floor from rocks, rebar and rough ground, and track guards protect it where tires roll in. Both are in our Berm Accessories category.
