Abstract: A modular berm system and method for installing the berm system about a containment area are provided. The berm system is formed by interconnecting a plurality of panels in an end-to-end arrangement. Corner pieces which enhance the modularity, stability and rigidity of the berm system are also provided. A continuous liquid barrier liner overlies the containment area and the supporting perimeter of panels. The liner blocks any discontinuities between panels. Discontinuities can be overlapped with flaps for protection of the liner.

Abstract: A storage tank system stores liquid containing debris. The sidewalls of the tank have a curved lower portion for receiving debris settling out of the liquid and for directing at least some of the debris to a base of the tank. The tank is also provided with a plurality of nozzles spaced longitudinally along the curved lower portion the sidewalls for directing flush liquid downwardly against the curved lower portion for flushing any residual debris remaining thereon towards the bottom of the tank. The tank has a skid equipped with rollers for improved manoeuvrability in a berm environment and manifolds for improved interconnectability with other tanks.

Abstract: A ground cover mat includes a first end interlock at a first end of the body which is adapted to interlock with a second end interlock at a second end of a like body. A second end interlock is provided at the second end of the body which is adapted to interlock with the first end interlock at a first end of a like body. A first side interlock is provided at a first side of the body which is adapted to interlock with a second side interlock at a second side of an adjacent like body. A second side interlock is provided at the second side of the body which is adapted to interlock with the first side interlock at a second end of an adjacent like body.

Abstract: A road mat includes a body having a first end, a second end, a first face and a second face. A first coupling is positioned at the first end has an outwardly extending portion extending outwardly from the first end adjacent to the second face, an angled portion extending from a remote end of the outwardly extending portion toward but not past the first face, and an inwardly extending retaining lip extending from a remote end of the angled portion back toward the first end. A second coupling is positioned at the second end is similarly configured with an outwardly extending portion extending outwardly from the second end adjacent to the first face, an angled portion and an inwardly extending retaining lip. The retaining lip of the second coupling engages the retaining lip of the first coupling preventing separation.
