A gabion consists of a box with a rectangular prismatic shape, which is an optical instrument made up of two cylinders inside which lenses are placed that allow distant objects to be seen enlarged, filled with stone with a metal mesh lattice or sometimes sand and earth for the use of civil engineering such as for the construction of roads and military applications for erosion control, which use caged rockfill, which is a work made with stones or cement or concrete blocks thrown at the bottom of the water to form a dam. defense against the waves of the sea.

The most common civil engineering use of gabions is to stabilize shorelines, stream banks or hillsides against erosion which is the wearing away of a surface caused by friction or rubbing, including temporary retaining walls, seepage of sediments by the water current that overflows its reservoir or natural or artificial channel, for small, temporary or permanent dams and for the formation of rivers or the lining of channels that can be used to direct the force of a water current of flooding around a vulnerable structure.

Gabions have some advantages over breakwater, which is a construction made with large rocks or cement blocks that are thrown to the bottom of the sea to raise a kind of wall or breakwater that serves as protection against the action of the sea due to its modality and capacity. to be applied in various ways.
