Railway ballast as gabion fill

Angular rock is the best gabion fill as it provides a good interlock and therefore less deformation of the face occurs. When using rounded river rock as gabion fill, it is recommended that you use the heavier 3/16th gabion baskets, which are less likely to deform under load. 3/16th wire is the preferred choice where an uniform architectural look is required, the gabions are likely to be sat or walked on, and when building narrow supported walls or columns
