Soil nailing is an in-situ earth retention technique used for reinforcing and strengthening existing soil by installing grouted steel bars (commonly referred to ‘nails’) into the soil at specific inclinations, depths and spacings.
Nails act as passive reinforcement elements; they are not prestressed but work by mobilizing tensile strength once the soil mass starts to deform or move. Nailing is commonly used to support retaining walls, stabilize slopes, and support excavation.
This technique is applied to increase and / or maintain the stability of soil mass and commonly used to support retaining walls, stabilize slopes, and for excavation support.
