They are made from hexagonal mesh in two forms. The first one is a hexagonal mesh gabion with an additional sheet of anchor mesh. The second one is a panel of hexagonal mesh with a formed headwall supported by supporting elements in the form of triangles of steel bars.
They are used to reinforce road and railway embankments in a form that ensures – and reinforces – the stability of these structures. In the first form, a gabion is made where an embankment has its edge, and the anchoring mesh is backfilled with the material from which the embankment is made and compacted. In many cases embankments are supported by a gabion on the other, opposite side, so that it is made between two gabions with anchor meshes overlapping each other.
