Summary
Highlights
Soil nailing is a geotechnical technique that stabilizes slopes, retaining walls, and excavations by reinforcing the soil with steel or fiberglass elements called soil nails.
The process involves drilling holes into unstable soil, filling them with grout to form high-strength steel nails, and then installing a corrosion-resistant facing (steel or wire mesh) over the surface to distribute loads and prevent collapse.
Soil nailing offers several benefits including versatility across various soil types, cost-effectiveness compared to traditional methods, minimal disruption to surrounding areas, and faster construction times.
Key applications include stabilizing slopes prone to erosion or landslides, reinforcing retaining walls to prevent movement, and providing temporary or permanent stabilization for excavations to ensure safety.
