  • Patent number: 8540456
    Abstract: A modular dike or barrier assembly includes straight and curved members that may be interconnected to form a barrier or dike wall surrounding a primary container. The members are hollow and include opposed side walls having integrally formed reinforcing ribs. The side walls extend at an acute angle relative to the base of the barrier to contain and redirect a surge flow directed toward the dike or barrier assembly. The interior surfaces of the side walls are closely spaced at locations spaced from the ribs and tend to abut for added wall reinforcement upon application of wall deflecting loads.
