Gabion-a double-twisted wire mesh container of variable sizes, uniformly partitioned into internal cells, interconnected with other similar units, and filled with stone at the project site to form flexible, permeable, monolithic structures such as retaining walls, sea wall, channel linings, revetments, and weirs for erosion control projects.

Gabions baskets are rectangular baskets made of heavily galvanized, double twisted, steel woven wire mesh. The single unit constructed baskets are assembled, laced together and then filled with stone to form a monolithic structure. Gabions and Reno mattresses are used for retaining walls, sound barriers, channel linings, slope stabilization, dams and weirs. They are particularly effective in restoring the environment and promoting vegetation growth.

Gabion Mattress-a double-twisted wire mesh container uniformly partitioned into internal cells with relatively small height in relation to other dimensions, having smaller mesh openings than the mesh used for gabions; revet mattresses are generally used for riverbank protection and channel linings.
