everything
Gabions are used everywhere these days even small firms like the ones I mentioned below are involved in gabions. The best place to see them is normally on motorways. Then they are often used in streams etc basically anywhere where you need to stop earth moving. Nowadays you can often find gabions in shopping precincts and supermarket car parks.

Gabions are bottomless baskets or metal frameworks filled with rocks, also known as panniers they are available in a variety of sizes they help solve erosion problems at low costs.
You can build gabions or build sea walls
Early gabions originated in Italy. The word gabion comes from the Italian word "gabbione" meaning "big cage". Leonardo da Vinci designed an early version of a gabion for the San Marco Castle, which he called a "Corbeille Leonard".
Gabions are commonly found in construction projects such as retaining walls, erosion control systems, coastal protection structures, and landscaping features like garden walls and benches. They are also used in military applications like bunkers and barriers.
the advantages are that it helps to protect the coast line by stopping the waves pounding at the cliffs. it does this by breaking the power of the waves when it hits the little rocks inside the cage. gabions are quite natural as rubble or pebbles can be used. gabions are also quite cheap and may be prefered to other coastal defenses such as sea walls. the disadvantages are that they may be considered unsightly by some people, they may take up quite a lot of space up on the beach as lots of gabions are needed to provide plenty of protection ( this makes the beach less desirable to people as the beach may seem more crowded) if the rocks inside the cage become worn down the whole cage will need taking out and replacing. if the gabions are stacked up in a wall and a lower one needs replacing this will mean taking out all the ones above it aswell before replacing it and rebuilding the wall. this would take lots of time and money! A timber crib retaining system offers an excellent alternative solution being generally faster and more simple to construct without the need of skilled or experienced labour. Timber crib can be used in both domestic and commercial applications and are considered by many as aesthetically superior to gabion baskets in addition to being environmentally friendly and sustainable.
