Process
The corrosion-resistant gabion baskets are placed in a competent formation, then connected to adjacent gabions using tie wire or clips. The gabions are then machine filled with stone and hand placed to reduce voids. The baskets are stacked on top of one another and are generally stepped back to construct a tiered or sloped wall. Tiebacks can also be applied to resist lateral loads.
