Soil nails may be the product of choice in applications where the vibrations from installing sheet piling or "H" piles may cause structural distress to nearby structures. Soil nails are generally installed to a shallower depth than tiebacks,
which might be an advantage if deeply installed tiebacks have to cross property lines and/or terminate under structures owned by other parties; or be otherwise obstructed. Soil nails work very efficiently in medium dense to dense sand with Standard Penetration Test values, "N" > 7 blows per 0.3m. They also are suited for low plasticity cohesive soil (clays) with SPT values of "N" > 8 blows per 0.3m, which also have soil cohesion values exceeding 1,000 psf through the entire depth of soil to be stabilized.
In many construction projects soil nails are used to retain the unstable soil mass. To accomplish this, soil nails are installed in an evenly spaced close geometric pattern. When installing a soil nail stabilization project, the soil nail
installations and the excavation must be accomplished in incremental depths of 1.2m to 1.8m until the final depth of cut is accomplished. Usually only one increment can be completed per day. Immediately following the incremental excavation of the soil and the soil nail installations, the vertical face of the soil is covered with a steel reinforced coating of shotcrete. Soil nails are passive structural elements and are not tensioned after installation. The soil nail gains pullout resistance from within the sliding soil mass in front of the slip plane and the stable soil mass located behind
the slip plane. The geometric system of soil nail placements creates an internally reinforced soil mass that is stable.
Notice that each soil nail shaft has a great number of helical plates with the same diameter. These helical plates are evenly spaced along the entire length of the shaft. By comparison, a tieback anchor has one or more helical plates
situated at the tip of the tieback. These helical plates generally increase in diameter along the shaft away from the tip.
Once a tieback anchor lead section is installed, extensions without helical plates are used to extend the helical plates
at the tip to the target depth. Soil nails, on the other hand, will always have identical evenly spaced, small diameter helical plates along the entire shaft from beginning to end.
