Gabion baskets have been used on an international scale for a long period of time and are preferred on government projects due to some of the following reasons:
1. High strength - the use of unweathered within the gabion provide high compressive strength.
2. Enhanced flexibility - woven steel wire mesh is used for the baskets, allowing movement over expansive soils without failure.
3. Creates employment opportunities - gabions require a lot of manpower, with little use of machinery required. Unskilled labor from local communities can be used and trained in a short time period.
4. Low environmental impact - vegetation can be incorporated into the gabion system to cover the gabion or mattress protection in a short time.
