A modular containment system, primarily for secondary containment of potentially hazardous materials, includes a series of interconnectable berm members which can be interlocked together to form virtually any desired containment perimeter. A sheet of flexible plastic material is laid over the containment area, and extends over the shoulders of the perimeter structure as a liner for the containment area. The liner is secured to the top of the perimeter structure, such as by a snap-in tube arrangement. For high stability of the perimeter structure, the modular berm members are hollow, formed of plastic material, to be filled with water or sand, as well as having a low, wide profile.

A containment system for receiving and collecting materials leaked or spilled from containers or dropped from an industrial process or other activity conducted over a containment area, comprising: a series of portable berm modules, each formed of a relatively lightweight material and having a hollow interior, and with a stable cross section to resist outward tipping, each berm module having a bottom with a load-bearing perimeter lying generally in a plane and having a base width which is great enough relative to the berm module\s height that with the berm module filled with water, it will not tend to tip outwardly when the containment area holds liquid of water\s density up to about half the height of the berm module, and with interconnection means on each berm module for interlocking the module with immediately adjacent modules so as to form a perimeter assembly with a plurality of the berm modules connected end to end to define the containment area, fill means permitting filling of the modules with water, sand or other suitable ballast material to add stability to the modules when assembled together into the perimeter assembly, and liner means formed of imperforate plastic sheet material, for overlying the containment area and extending at least partially up onto the berm modules of the perimeter assembly, to thereby contain solid or liquid materials within the containment area.
