The method of soil nailing is a recent introduction that may be regarded as a form of in-situ reinforced soil in which reinforcement is installed in natural soils rather than in selected fills. As a result the procedures employed for its design and construction differ from conventional reinforced soil in several respects and therefore require special consideration for purposes of specifying its use for different applications. This report describes the procedures and background to a specification on soil nailing. It also provides a selection of suggested specification clauses that could be used in both earthworks and structural applications of highway engineering. The suggested clauses have been drafted to apply to the two principal methods currently used, namely drilled and grouted and driven systems, and could be employed directly or adapted to conform to a particular application.
