Soil Nailing for Erosion Control
A Southwestern University graduate, Charles Scharf is a resident of Barrington, IL. Since 1982, Charles Scharf has been the owner and president of Erosion Specialists Inc. in Barrington, IL.
Excavation and construction can lead to many erosion problems, but numerous solutions are available for these situations. Where temporary excavation shoring, slope stabilization, existing bridge abutments, or even permanent retaining walls require reinforcement, soil nailing wall construction can be an effective solution.
This technique brings stability to the soil where landslides might occur. Soil nailing means that steel bars are driven into the earth to reinforce and anchor the ground. Thus, the rods function similarly to nails to lock the soil into place.
Holes for the rods must be pre-drilled and usually have a diameter of four inches. The steel bars are between 0.8 inches and 2 inches in diameter and yield 62 kilopounds per square inch (ksi) to 70 ksi in tensile strength.
Soil nailing is appropriate for projects with tight spaces and irregular shapes and where minimum shoring is required. However, it is inadvisable in areas with a high water table or in locations with incompatible sand and gravels.
