Soil nailing is a construction method used to maintain or increase the stability of soils by installing rein forcing elements (nails) according to the principles for the execution of geotechnical works. The soil rein forced with nails forms a supporting structure. The nails are primarily subjected to tensile loads. In addition, bending and shear loads may occur as well. The structure must be so designed that the nailing forms a redundant system. One single nail may not serve as the only load-bearing element.  


self-drilling anchor system increase the load-bearing capacity of the entire structure and act as a group of elements, withstanding tensile and shear forces acting on the self drilling anchor system. The center-to-center distance of nails must be chosen so that they are able to act as a complete nailing system. Prior to nail installation, the excavation face is generally supported by shotcrete, precast concrete elements, mesh, or geotextiles. The design of a nail head construction depends on the application and the intended lifetime of the structure.
