Gabion and rock mattresses are baskets made of steel wire mesh, laced together and filled with stones to form monolithic structures that can provide a cost effective and sometimes unique solution to many problems in river works, soil stabilisation, flood and scour protection and coastal defence.
From a 4000 year old idea, modern gabions were first produced in the late 1800's and are now installed in numerous locations in Tasmania and throughout the world.
Gabions offer:
Flexibility.
Gabions tolerate differential settlement without fracture. This is especially important when building on unstable ground or in marine or river applications where waves or currents are a consideration.
Permeability.
Hydrostatic heads do not develop behind gabion structures because of their permeable nature. They are free draining structures ideal for slope stabilization and retaining walls.
Durability.
The durability of gabion structures increase with age. As consolidation takes
place, silt and soil collect in the voids and vegetation becomes established.
Ecology.
Gabions permit the growth of vegetation and maintain the existing environment,
they provide attractive and natural building blocks for decorative landscaping.
Cost Effectiveness.
Requiring unskilled labour and limited plant, a gabion structure can be built
anywhere at low cost.
