A gabion wall is a retaining wall made of stacked stone-filled gabions tied together with wire. Gabion walls are d back with the slope, rather than stacked vertically.
Gabion baskets have some advantages over loose riprap because of their modularity and ability to be stacked in various shapes; they are also resistant to being washed away by moving water. Gabions also have advantages over more rigid structures, because they can conform to subsidence, dissipate energy from flowing water, and drain freely. Their strength and effectiveness may increase with time in some cases, as silt and vegetation fill the interstitial voids and reinforce the structure. They are sometimes used to prevent falling stones from a cut or cliff endangering traffic on a thoroughfare.
Variations in design
In the medieval era, gabions were round cages with open tops and bottoms, made from wickerwork and filled with earth for use as military fortifications. These early military gabions were most often used to protect sappers and siege artillery gunners.
