Using native soils as the reinforced fill material in Mechanically Stabilized Earth (MSE) structures can be problematic especially if the native soils contain a large percentage of fines (d<0.075mm) and are poorly graded. Several case histories of TerraSteep retaining walls, a welded-wire-form faced MSE structure using such native soils in the Greater Toronto Area (GTA) have been reviewed and discussed in this paper with respect to their design, construction and performance during and after installation of the walls based on monitoring data.
