The use of gabions as an effective solution to combat erosion and to stabilise and strengthen embankments has been in evidence for several centuries. Rivers, coasts, roads, and railways can all be subject to continuous or fluctuating erosion, demanding planned defences that counteract the forces involved.
Gabion baskets are used in many modern civil engineering schemes to provide a more environmentally friendly solution to mass concrete structures. Using gabions as an alternative to the more traditional concrete structures allows you to fill them with local stone vegetation, giving the product a more attractive natural appearance. They are manufactured from welded or woven wire mesh and can be quickly erected and filled without special skills or machinery thereby keeping costs to a minimum.
Bi-axial welded mesh gabions are manufactured from a square mesh, normally of opening size 75.0mm × 75.0mm where the longitudinal wires are welded to the cross wires at their intersection points. Hexagonal woven mesh gabions are manufactured from a mesh that has a hexagonal opening which is formed by twisting pairs of wire together with one and a half turns (sometimes referred to as triple or double twist). Gabions are available in a number of wire diameters and coatings to suit the application or can be manufactured in a combination of mesh-wire specifications to provide economy in supply. The resultant gabions’ flexibility is dependent upon the choice of wire diameter.
Where two types of stone fill are required, additional loose panels can be supplied and fitted on-site to separate the two types of fill materials.
