Gabion walls are rectangular wire mesh baskets filled with rock at the project site to form flexible, permeable, monolithic structures such as gabion retaining walls for railway ,road projects. They are also used for erosion control for bank stabilization, channel linings, and gabion weirs. Gabion strength lies in their double twisted hexagonal mesh of steel wire which is reinforced by selvedges of heavier wire running along the edges and by transverse diaphragms. The wire will not unravel even when cut. Assembly is easy, requiring no specialized labor and nearby rock is used for fill.
