Pvc Coated Hexagonal Mesh Woven Stone Filled Gabion Baskets
Stone Filled 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.
Stone Filled Gabion Box Applications:
• Control and guide of water or flood
• Flood bank or guiding bank
• Prevention of rock breaking
• Water and soil protection
• Bridge protection
• Strengthening structure of soil
• Protection engineering of seaside area
• Seaport engineering
• Isolation walls
• Protection of road
Stone Filled Gabion Box Advantage:
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 stones.
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.

Woven 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.
