Gabion baskets are available with either PVC or galvanized finishes.
Gabion basketconsist of rectangular units, fabricated from a double twisted hexagonal mesh.Gabion baskets are wire mesh baskets filled with rock, and are strategically placed to form retaining walls and erosion control barriers.
According to gabion manufacturer Maccaferri Group, underwater gabion baskets are placed in channels and along erosion-prone banks. Often placed in groups or specialty configurations, the baskets minimize wave action and discourage further soil loss. At the same time, water drains easily through the mesh baskets. If the rocks becomes too worn or the box too rusted, you need remove the gabion box. If the box which is at the bottom of a pile needs replacing , you have to remove all of them, which can make the work expensive and hard. Meantime because of the size and weight of most gabion boxes, you need heavy lifting gear to move them into place.
