The Ultimate Model containment berm from UltraTech International, Inc., Jacksonville, FL, is designed to contain spills from heavy vehicles. The entry and exit walls are supported every 12 in. with a patented two-way "living hinge". The end walls don’t need to be lowered manually for vehicles to drive over them.

Once a vehicle has entered or exited, the walls automatically spring back to the vertical position. PVC assemblies hold the long sidewalls upright. Feet are swiveled to lower the sidewalls for storage or transport elsewhere.

The berm is constructed from Coploymer 2000, a new reinforced polymer-coated, chemically resistant fabric.
