Soil nailing uses grouted, tension-resisting steel elements (nails) to reinforce in situ soils and creating a gravity retaining wall for permanent or temporary excavation support.

Common uses
- Stabilize slopes and landslides
- Support excavations
- Repair existing retaining walls

Process:-
Soil nail walls are generally constructed from the top down. Typically, soil is excavated in three to six feet deep stages. After each excavation stage, near-horizontal holes are drilled into the exposed face at typically three to six foot centres. Tension-resisting steel bars are inserted into the holes and grouted in place. A drainage system is installed on the exposed face, followed by the application of reinforced shotcrete wall facing. Precast face panels can also be used. Bearing plates are then fixed to the heads of the soil nails. This installation process is repeated until the design wall depth is reached. The finished soil nails then produce a zone of reinforced ground.
