Special Environments.

In Australia there are areas where local conditions create an increased likelihood of corrosion. Special consideration should be given to material selection and design in these areas. They include:

Coastal Environment

Within 1000m of the coast, characterised by: Light salt deposits A frequent smell of salt in the air

Acidic Soils.

When constructing gabion retaining walls in strongly acidic soils (PH over 5.5), the soil and the corrosive groundwater must be separated from the gabion structure by using geotextile fabrics and a properly designed drainage system.

Galvanisation.

Galvanising protects the gabion steel in two ways

PVC Coating.

PVC coating does not improve the gabions resistance to damage from flood debris impact.

15 year Study.
