wire mesh

 gabion is a rectangular wire mesh box made from double twisted hexagonal mesh of steel wire, additionally reinforced by selvedges of heavier wire running along the edges and by transverse diaphragms filled with rock at the project site to form flexible, permeable, monolithic structures such as retaining walls for commercial, industrial and road projects. They are also used for erosion control for bank stabilization, channel linings, and weirs. These mesh boxes are delivered to site flat-packed, whereupon they are assembled, lifted into position, and filled with durable rock. Lacing and bracing wire are used to assemble and join the gabion units. Woven units can also be easily amended on site and shaped to suit project requirements
