Gabion description :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. 

Diaphragms: 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
