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 2m x 1m in plan.
Standard mattress sizes are 3m x 2m & 2m x 2m in plan and available in depths of 0.17m and 0.3m respectively. These are typically supplied in a Galfan coated wire with a PVC coating on top as traditionally they are laid on the beds of watercourses or beneath gabion walls to provide erosion protection and under scour. Once filled with stone or rock and the lid closed, they form monolithic blankets.
