TerraNail is a passive geotechnical anchoring system consisting of a range of bars and adapted accessories, allowing its use in several civil engineering applications. The bars are either fully threaded (Hot threaded) solid bars or rope threaded hollow bars. On-demand, the bars and the accessories can be coated with a corrosion protection system (hot-dip galvanization or epoxy or double corrosion protection with hot-dip galvanization and epoxy). The fundamental concept of TerraNail consists of reinforcing the soil or rock mass by passive inclusions, closely spaced, to create an in-situ coherent gravity structure. Hence, it increases the overall shear strength and stability of the in-situ soil or rock strata and restrains its displacements. Installation of TerraNail for any permanent solution involves basic steps – drilling, placing of the bars, grouting and securing the nail end.
