Questions and answers

How much does the Berg Flex Wall Drive Over & Through Containment Berm hold?

Up to 1,203 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. It is built for drive-in, drive-out use; the low walls let tankers and heavy equipment roll in and out without ramps.

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.
