Modular wall sections and corners can be easily assembled to create spill containment areas of nearly any size or shape. The system features a heavy-duty, 30 mil liner and a rugged, impenetrable barrier to effectively capture leaks and spills. This design allows for creating large, semi-permanent containment areas, offering significantly greater gallon capacity than shorter-walled systems. Additionally, the versatile system can be disassembled for reuse at future sites. Unlike other containment solutions, the Tundra-Containment Wall is not secured to the substrate. It is ideal for use in various environments such as parking lots, sandy or rocky soil, muddy terrain, frozen ground, or concrete surfaces.
