Abstract: A reusable liquid containment system to capture and control spills or run-offs of hazardous liquids. The containment system consists of a reusable berm device which forms a perimeter dimension and conforms to various terrain elevations. The berm device consists of uniform elongated rectangular shaped foam units having an elastic memory, a rigid base, all encased in a fluid resistant protective cover with grommet protected openings to provide for horizontal and vertical connection. The berm devices are positioned in a single or multiple course to achieve appropriate elevation, with tapered berm devices to address varying topographic elevations. The containment system also consists of a draped containment liner or woven, knitted or braided fabric, or thermo-plastic material. The containment system allows wheeled vehicles and related equipment to cross without compromising the integrity of the perimeter berm and liner.
