GABIONS are double-twisted wire mesh baskets of variable sizes, uniformly partitioned into internal cells, interconnected with other similar units. They are filled with stone at the project site to form flexible, permeable, monolithic structures, such as retaining walls, sea walls, channel linings, revetments and weirs for erosion control projects.
The wire mesh used for the gabions is fabricated from heavily galvanized coated wire conforming to BS443 Standards; and woven into double-twisted hexagonal shaped mesh. The double-twist of the woven wire mesh provides integrity, strength and continuity to the structure by adding a non-raveling effect that prevents any accidental damage from spreading.
When gabions are to be placed in aggressive environments, an additional Polyvinyl Chloride (PVC) coating can be applied on the galvanized coated wire by extrusion before the weaving of the mesh. The PVC coating will protect the wire and provide further resistance against chemical, biological and corrosive agents.
Stainless Steel Gabions
Gabions constructed of stainless steel are available in common Type 304 and MARINE GRADE Type 316L Stainless Steel wire mesh - see description and differences below.
Gabions constructed of Type 316 Stainless Steel are considered the most effective construction material with the best resistance to salt water corrosion. Stainless Steel construction may be relatively expensive but it offers the longest life in high salinity coastal applications.
Also note that vegitated gabions made of stainless steel (an inert material) offer an important component to the establishment and growth of natural vegitation in waterways and soil banks while providing strong protection from the onset .
Gabion structures are able to develop and integrate with the surrounding environment, permitting the preservation or restorations of the natural environment. They are often used by architects as decorative elements of the landscape.
