Gabion baskets are wire fabric containers, uniformly partitioned, of variable size, interconnected with other similar containers and filled with stone at the site of use, to form flexible, permeable, monolithic structures such as retaining walls, sea walls, channel linings, revetments and weirs for earth retention. Gabion basket fabric is made of steel mesh with the opening type 8x10 mesh commonly. The diameter of the wire mesh has normally two types: 2.7 or 3.0 mm. The gabion element is in the shape of block or regular cube size. These special wire bins are made of robust wire, filled with the vibrations at the quarry and transport are accompanied by the lifting straps.
Soil erosion is an ever present problem and gabions baskets have proved to be a lasting solution around the world. The earliest known use of gabion-type structures was for bank protection along the Nile River during the era of the Pharaoh. The lasting appeal of gabions lies in their inherent flexibility. Efficiency in gabion basket structures, rather than decreasing with age, actually increases. During early periods of use, silt and vegetation will collect with the rock fill to form a naturally permanent structure and may be used to remove solid pollutants or "floatables" from the water.
Gabion baskets are made of hexagonal galvanized or PVC coated double-twisted mild steel wire.
Features of Gabion Basket
Double-twisted hexagonal steel wire mesh structure can tolerate huge forces without breaking or cracking. It adapts itself to some degree of movement.
Gabion basket has a very long life and durable structure.
The hexagonal wire mesh structure filled with stones provide an effective permeability throughout the structure, they are self-draining.
It can absorb the huge amount of energy and very strong under tension generated by the nature.
