Caltrans Geotechnical Manual Soil Nail Walls Soil nails are passive reinforcing elements that are installed and grouted in sub-horizontal drilled-holes to form a composite mass. Soil nails can be effective in increasing stability of a slope, or in constructing a wall that requires top-down excavation. In addition to this module, the documents that govern or guide the investigation, design, and reporting for Soil Nail Walls include: FHWA Geotechnical Engineering Circular (GEC) No. 7 (2015). Memos to Designers 5-19, Earth Retaining Systems Communication Geotechnical Manual , Foundation Reports for Earth Retaining Systems Design and performance advantages of soil nail walls include: Less right of way needed than competing systems, such as ground anchors;. Less disruptive to traffic and cause less environmental impact.
