Abstract
A containment berm formed of a flexible, substantially impermeable polymer material defining a ground section with a plurality of sidewalls extending upward from the ground section. A plurality of hinges are positioned on an interior of the containment berm, with the hinges having first and second aims rotating on a pin, the first arm engaging a first sleeve on one of either the ground section or a sidewall, and the second arm engaging a second sleeve on the other of the ground section or the sidewall. The second sleeve is configured to allow the hinge to slide far enough away from the first sleeve to allow the first arm to disengage from the first sleeve.
