Gabions are rectangular cages made of double twist hexagonal wire mesh, filled with appropriately sized rock. They are used as retaining walls, toe protection for slopes or as weirs. The flexibility of gabions allows significant deformation without affecting the structural integrity of a wall. If revegetation of a structure is required, the environmentally friendly nature of gabion cages does not impede this process. Gabions are available in the following standard sizes: L(m) x w(m) x h(m) 1m x1m x 1m 2m x 1.5m x 1m 2m x 0.5m x 0.5m 2m x 1m 0.5m 2m x 1m x 1m 4m x 1m x 0.5m 4m x 1m x 1m 6m x 2m x 0.5m
