The hesco barriers is a modern gabion primarily used for flood control and military fortifications. It is made of a collapsible wire mesh container and heavy duty fabric liner, and used as a temporary to semi-permanent levee or blast wall against explosions or small-arms. It has seen considerable use in Iraq and Afghanistan.
1, Ends, diaphragms, front and back panels are placed upright on the bottom section of wire mesh.
2, Secure panels by screwing spiral binders through the mesh openings in adjacent panels.
3, Stiffeners shall be placed across the corners, at 300mm from the corner. Providing a diagonal bracing, and crimped over the line and cross wires on the front and side faces. None are needed in interior cells.
4, Gabion box filled with graded stone by hand or with a shovel.
5, After filling, close the lid and secure with spiral binders at the diaphragms, ends, front and back.
6, When stacking tiers of the welded gabion box, the lid of the lower tier may serve as the base of the upper tier. Secure with spiral binders and add pre-formed stiffeners to exterior cells before filling with graded stones,.
