    Soil Nails. Soil nails are a more modern version of ground anchors. They are installed in increments during excavation and construction. Holes are dug and then long steel nails are inserted and cemented into place to hold soils in place or support structures. Compared to ground anchors, soil nails are more popular for steep slope excavations and stabilization.
