Abstract
A subsurface support is provided in the form of a soil nail. The soil nail has asperities formed on the outer surface thereof to improve the pullout capacity of the soil nail. The asperities can take a number of forms to include indentations, deformations and threads formed on the outer surface of the soil nail. Optionally, a stinger may be attached to a distal end of the soil nail to further enhance the pullout capacity of the soil nail.
