Gabion Baskets

TWISTED WIRE GABION BASKETS

Gabions are rectangular wire mesh baskets filled with rock at the project site to form flexible, permeable, monolithic structures such as retaining walls for commercial, industrial and road projects. Gabion baskets are made from double twisted, hexagonal woven wire mesh. The wire used to manufacture the gabion baskets is fabricated from soft tensile, heavily galvanized steel, which is also available with an extruded PVC coating for additional corrosion protection, when required by the application. 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. Lacing wire is used to assemble and interconnect empty units and to close and secure stone-filled units. Once assembled, the baskets are filled on site with durable stone. Gabion Baskets are also used for erosion control for bank stabilization, channel linings, and weirs. Their strength lies in their double twisted hexagonal mesh of steel wire which is reinforced by selvedges of heavier wire running along the edges and by transverse diaphragms. The wire will not unravel even when cut. Assembly is easy, requiring no specialized labour and they are easy to install. They are ideal for any situation where a retaining structure is required which is also aesthetically pleasing and environmentally friendly. Since Gabion baskets are permeable, they integrate and adapt in harmony with their surroundings, allowing environmental growth and preservation. Loss after Wear (1)
