Gabions are rectangular wire mesh baskets filled with rock at the project site to
form flexible, permeable, monolithic structures
such as retaining walls for commercial, industrial and road projects.
They are also used for erosion control, bank stabilization,
channel linings, and weirs. Gabion structures yield to earth movement but maintain full
efficiency and remain structurally sound. They are quite unlike rigid or sem-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.
