GABION MATTRESSES

Gabion mattresses are box units where the plan area is large compared to its height. Each unit is subdivided into compartments normally to give cells 2mx1m in plan.

Typically standard sizes are 3mx2mx0.3m and supplied in a Zinc or PVC/Zinc coated wire.
The units are laid on the bed of rivers. Once filled with stone or rock and the lid closed, they form a blanket erosion control system.
Gabion Mattresses are also used to provide underscour protection to retaining structures.
