G - Pg. 125

G Gabion Walls 125 A gabion is a metal container filled with earth and/or stones. The caged riprap is then used for erosion control and to build dams or foundations. From the Italian word gabbione, meaning `big cage', gabion walls were first developed as a military structure to protect field artillery gunners. Nowadays, gabion walls are used to stabilise shores against erosion and are also used as retaining walls or temporary floodwalls. The gabion is increasingly seen as a viable aesthetic and construction technique for much contemporary architecture. This gabion wall (below) is used to stabilise a slope or mountain by a road.
