Multiple twisted hexagonal woven galvanized or PVC coated steel
Gabion Box are multiple twisted hexagonally woven galvanized or PVC
coated steel wire mesh compartmented baskets with a rectangular box
shape. The compartments are of equal dimension and are formed by
internal diaphragms. The compartment is filled with natural stone
and the diaphragms assure minimum stone migration within the
basket. Thus providing even distribution of the stone even in
abnormal conditions, and adding strength to the container to help
retain its rectangular shape during the filling operation.
Gabion box is consist of rectangular units, fabricated from a
double-twisted hexagonal mesh, filled with stones. In order to
reinforce the structure, its edges with a wire having a thicker
diameter than the mesh wire. Gabion boxes be divided into cells by
diaphragms at every 1 meters.

Flexibility: Flexibility is an important benefit of any gabion
structure. The double-twist hexagonal mesh construction permits it
to tolerate differential settlement without fracture. This property
is especially important when a structure is on unstable soil
conditions or in areas where scour from wave action or currents can
undermine the toe of the structure and cause structural settlement.
Durability: Gabions support plant growth which provides a live
coating for the wire mesh and stones, adding to their durability.
Generally, the wire mesh is needed for the first few years of the
structure’s life; later the void between the stones is filled with
soil, silt, and plant roots which act as a bonding agent for the
Strength: Steel wire hexagonal mesh has strength and flexibility to
withstand forces generated by water and earth masses, and the
pervious nature of the gabion allows it to absorb and dissipate
much of that energy. This is evident on coast protection
installations where gabion structures remain effective long after a
massive rigid structure fails. Additionally, the double twisted
hexagonal mesh won’t unravel if cut.
Permeability: Gabion walls are previous to water and stabilize
slopes by the combined action of draining and retaining, precluding
the development of hydrostatic pressure behind the gabion wall.
Drainage is accomplished by gravity, as well as evaporation as the
porous structure permits air circulation through it. As plant
growth develops within the structure, the process of transpiration
assists in removing moisture from the backfill – a much more
efficient system than weep holes in standard masonry walls.
Low cost: Gabion systems are more economical than rigid or
semi-rigid structures for the following reasons:
It requires little maintenance, Its installations does not require
skilled labor and stone fill is available on site or from nearby
quarries, It requires little or no foundation preparation, as the
surface needs to be only reasonably level and smooth. Gabions are
porous, requiring no costly drainage provision
Ecology: Gabions is an environmentally sensitive solution to slope
stabilization. It has already been mentioned that stone fill is
done with natural stones making the gabions, naturally porous
allowing interaction between the land and the water table and also
persuades deposition of soil in the smaller voids between the stone
fill during drainage that again promote vegetation growth.
Aesthetics: Gabions supporting vegetation has already been
discussed; in some case the vegetation growth is so intense, making
the gabion structure invisible, and pleasant to look at. Again if
additional effort is given during construction, the gabion can
create really pleasing structure with or without vegetation. Unlike
other types of materials such a modular block walls the gabion
stones do not discolor due to drainage.
