How thick do gabion walls need to be?
Gabions can be cut on site to achieve your required dimensions. The standard thickness for walls up to 3m in height is 3mm. 4mm is the architectural spec, 5mm is what we would refer to as the military spec or for use on higher walls.
How deep should a gabion retaining wall be?
