Soil Nails are a construction technique that are used in slope remediation as well as new construction. Soil Nails are passive elements made of solid or hollow stem bars that are installed into the slope face at an angle slightly below horizontal. Soil Nails are encased in grout to bond them to the surrounding soil and to provide a level of corrosion protection. The most common application of Soil Nails are in Shotcrete-Soil Nail Retaining Walls. Shotcrete-Soil Nail Retaining Walls are constructed from the top down using 5 ft. vertical cuts. Typically the soil nails are installed using 5 ft. spacing (horizontal and vertical). The design of Soil Nails depends on several variables including retained height, amount of soil above retained soil, type of soil, etc.
