Soil Nailing

Soil Nailing is used in ground stabilisation works such as slopes, embankments and pavements. It increases shear, friction and tension strength of soil. Solid or hollow reinforcing steel bars are inserted into closely spaced pre-drilled holes and grouted into place.

Soil nails increase stability by increasing the normal force, and consquently the shear resistance, that can be a applied along the slip plane in frictional soils.

The diameters of the reinforcing bars vary from 25 to 30 mm and are spaced about 1 m apart. Nail lengths are 70 to 10% of the nail wall height.
