Woven Gabions are divided into cells with diaphragms (usually spaced at 1 meter or 3’ intervals), whose function is to reinforce the structure. The mesh (except for the diaphragms) is reinforced on all edges with wires of a larger diameter to strengthen the gabions and facilitate the assembly and installation.
Woven Gabions consist of rectangular units, fabricated from a double-twisted hexagonal mesh. Filled with stones, gabions become large, flexible and permeable elements from which a broad range of structures may be built. Gabions and mattresses are widely used for hydraulic and geo- technical control such as retaining walls, riverbank protections, weirs, channel linings etc.

Packing:
For easy handling and shipping, the gabions are supplied folded flat. A color stripe applied on the side of each folded gabion identifies the size.
Loading:
Usually, gabions will be loaded into 40ft containers to save cost.
