Gravity walls are used in infrastructure, landscape or urban projects for the construction of retaining walls. The sometimes rugged relief of some west African landscapes (such as the city of Abidjan for example) creates the need to build these gravity walls for the development of land and infrastructure (roads, railways, etc.). Industrial and mining sites (e.g. crushers) also require support, sometimes at great heights.
Gabion walls have great advantages over other retaining techniques (such as concrete or rockfill): their flexibility (gabion walls are the only structures capable of undergoing differential settling without damage), their drainage capacity (the porosity of each gabion allows water to drain through the wall), their speed of implementation and their immediate effectiveness.
