Soil Nails

Soil nails are bars installed within an excavation or slope to provide reinforcement to an earth retention structure. They differ from tie backs in that they are considered passive elements and are not actively loaded in tension like a prestressed ground anchor. Soil nails are used in combination with a steel grid cover and shotcrete. As a system, the soil nail, grid cover, and shotcrete act as a coherent mass with enough strength to resist the overburden pressure of the surrounding soil mass, as well as any surcharge pressure.

In comparison to tie back anchors, soil nails have a few significant benefits. The equipment required to install soil nails is relatively small and mobile, providing a distinct advantage for applications with tight spaces or noise control issues. Using soil nails is typically a more flexible construction technique, allowing for simpler on-site modifications. Also, soil nails are installed early on in the construction process, limiting the disturbance on adjacent structures.
