Soil Nails are an excavation support system where the nails are drilled (typically at an angle) through mesh face into the earth to pin it back. The nails are installed as the soil is excavated, usually in 5-ft lifts. Customarily, shotcrete is sprayed over the final nail and mesh combination to provide the finished wall. Soil nail and shotcrete walls can be used for temporary or permanent support.
