Standard Designs of Gabion Retaining Wall
A gabion is a cage, cylinder, or box full with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building, and military applications and landscaping.
Here are some different designs based on different heights:
1m high wall
A 1m high wall is very easy to build and it requires 1m x 1m x 1m or 2m x 1m x1m baskets. The smaller size is recommended if the length user have to cover is small as it will lessen transport costs. User can also use 1/2m deep baskets this will save on the cost of fill but will decrease the strength of the wall and is recommended only in situations where the bank is fairly secure.
2m high wall
Gabion baskets are a mass retaining system accordingly, to construct a wall for the higher area which requires retaining; for that reason the wall must be heavier enough. For a gabion wall’s standard design the structure is like a pyramid. As a matter of fact, for every 1m expansion in wall height, the bottom row basket depth should be expanded by half a meter.
3m high wall
In this example the top 2 rows are the same as a 2m wall but with a .5m increase in the depth of the bottom row.
The bottom row is 2 meters deep middle row 1.5m deep and top row 1m deep. In general usage of 2m x 1m x 1m baskets bottom row 1.5m x 1m x 1m baskets in the middle row and 1m x 1m x 1m or if possible 2m x 1m x 1m baskets going sideways on the top row.
