Patent ID: 8590727

Claim:
A modular berm system comprising: a plurality of modular panels, each panel having a top edge, a base and opposing connecting ends defining a supporting surface therebetween, the panels interconnected at the opposing connecting ends of adjacent panels to form an upright perimeter wall resting upon the base on a floor of a containment area enclosed by the perimeter wall, the opposing connecting ends of the adjacent panels forming discontinuities therebetween; a liner overlying the floor and the supporting surfaces of the perimeter wall; a flap corresponding to each discontinuity, each flap resting on the supporting surface and extending over the discontinuity for preventing extrusion of the liner therethrough, wherein the liner forms a substantially continuous liquid barrier for retaining liquids isolated from the floor and within the containment area, the liner further extending over the top edge of the panels; and a plurality of fasteners for retaining the liner to the top edge of the panels.
