Gabions are wire mesh baskets or cages built from galvanised steel, containing cobbles or crushed rock, slate, and other similar rockfill materials, depending on the use. They are used in landscaping, internal architecture and for civil engineering purposes.
One common application for gabions is the construction of walls or fences, for aesthetic purposes, as well as functional needs like preventing erosion. The wire baskets are stacked neatly like building blocks, creating a sturdy and powerful barrier.
As compared to brick walls, the advantage of gabions is the low maintenance required compared to brick walls. Gabions are also cost effective and stable. In addition, the natural look is great for creative landscaping. However, a disadvantage would be the cost of assembling gabion walls, due to the skill and machinery required to lift heavy sections.
