They are made of hexagonal mesh in the form of rectangular boxes. Filled with aggregate, they are used for making retaining walls, supporting structures, building up of breaches and regulatory structures on water courses.
Depending on the aggregate used, a structure with different bulk density can be obtained. This is important because these structures fulfil their intended function through their mass.
In order to reduce the size of a gabion structure, a set is used in the form of a gabion of smaller weight and volume anchored in the ground with ground anchors or soil nails.
Depending on the design requirements, gabions are made of wire mesh with various anti-corrosion coatings, including stainless wire mesh.
