Gabions are wire fabric containers, uniformly partitioned, of variable size, interconnected with other similar containers and filled with stone at the site of use, to form flexible, permeable, monolithic structures such asretaining walls, sea walls, channel linings, revetments and weirs for earth retention.

Soil erosion is an ever present problem andgabions have proved to be a lasting solution around the world. The earliest known use of gabion-type structures was for bank protection along the Nile River during the era of the Pharaoh. In the subsequent 7, 000 years since its initial use by the Egyptians, the gabion system has evolved from baskets of woven reeds to engineered containers manufactured from wire mesh. The lasting appeal of gabions lies in their inherent flexibility.

Gabion structures yield to earth movement but maintain full efficiency and remain structurally sound. They are quite unlike rigid or semi-rigid structures which may suffer catastrophic failure when even slight changes occur in their foundations. Highly permeable, the gabion structures act as self draining units which "bleed" off ground waters, relieving hydrostatic heads. Interstitial spaces in the rock fill dissipate the energy of flood currents and wave action.

Efficiency in gabion structures, rather than decreasing with age, actually increases. During early periods of use, silt and vegetation will collect with the rock fill to form a naturally permanent structure and may be used to remove solid pollutants or "floatables" from the water.

Gabions and mattresses may be purchased as as assembled baskets, as unassembled panels, or in roll stock form. Roll stock may utilized to build continuous gabion structures up to 300 feet in length or mattresses up to 150' in length.

Gabions Features:

Economic. Just fill the stone into the gabions and seal it.
Simple installation. No special technology needed.
Weather proof under natural destroy, corrosion resistant.
No collapse even under big scope of deforming.
Sludge in the stones is good for plant growing. Mixed to form a integrity with the natural environment.
Good permeation can prevent the damage by hydrostatic.
Less transport freight. It can be folded together for transport and further installation.

gabions applications:

Control and guide of water or flood
Flood bank or guiding bank
Preventing of rock breaking
Water and soil protection
Bridge protection
Strengthening structure of soil
Protection engineering of seaside area.
