Abstract: A method of installing a reusable security barrier is presented that allows quick installation and removal. In one preferred embodiment, the method comprising providing precast concrete panels having a generally rectangular profile elevation, digging a foundation trench having a length equal to or longer than the panel width, lifting and placing the panel such that a portion of the panel is inserted inside the trench and a portion extends generally vertically upward from the trench forming a barrier, and filling and packing the portion of the trench unfiled by the panel with a filler material to provide a solid foundation. The method can further comprise utilizing multiple panels placed side edge to side edge with their bottom portions inserted inside a trench to form a longer security barrier. The method can further comprising removing the precast concrete panels from the trench for reuse in a second site security barrier when the original security barrier is no longer needed.

Abstract: A security barrier is presented for preventing unauthorized persons or vehicles from easily crossing a border. In one preferred embodiment, the security barrier is suitable for installation in a waterway and comprises: (1) a plurality of piles, each pile having a bottom end embedded into the earth and a top end extending vertically upward; (2) an open security grid juxtaposed between and secured by the piles, wherein the grid preferably has a bottom end that extends downward below the surface between the piles toward the earth; (3) at least one rigid wall panel also juxtaposed between and secured by the piles on top of the open security grid, thereby forming a security barrier that allows water, air, aquatic life, and birds to pass through the barrier, but restricts the movement of humans and vehicles across the barrier.
