Gabions are used in many situations including the stabilization of earth movement and erosion, river control, reservoirs, canal refurbishment, landscaping and retaining walls. They can be manufactured in welded mesh or woven wire. Welded mesh gabions are faster to erect and do not need tensioning. This allows them to keep their shape, to be free from bulges and depressions and fit easily against the wall. It is possible to cut holes in them if needed to pass pipes etc through and they can be machine filled.
Gabion basket
Gabion are baskets manufactured from 8×10 double twisted hexagonal woven steel wire mesh, as per ASTM A975-97 Gabions are filled with stones at the project site to form flexible, permeable, monolithic structures such as retaining walls, channel linings, and weirs for erosion control projects. The steel wire used in the manufacture of the gabion is heavily Galfan (zinc-5% aluminum-mischmetal [Zn-5 Al-MM] alloy) coated soft temper steel. A PVC coating is then applied to provide additional protection for use in polluted, contaminated or aggressive environments: in salt, fresh water, acid soil or wherever the risk of corrosion is present. The PVC coating has a nominal thickness of 0.02 in. (0.50 mm). The gabion is divided into cells by diaphragms positioned at approximately 3 ft (0.9m) centers. To reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter. Gabions shall be manufactured and shipped with all components mechanically connected at the production facility.
