“Soil-nailing technique, for the support of excavation faces or slopes under safety conditions, is very useful and advantageous for urban environments with a high environmental value where traditional support works do not can be used.
The ground nailing uses passive reinforcement elements, namely nails (nail), which are installed in the ground, cemented or in direct contact with the ground, with a somewhat reduced spacing; The nails are then connected by means of netting or coatings, which do not bear the sole function of conferring continuity in the distribution of the forces and to protect the face from the surface erosion.”
