A soil nail wall is an earth retention system used for deep excavations.
how they work:
Soil nail walls are created when steel reinforcing elements (nails) are installed and grouted over a
regular pattern to create a soil that acts as a coherent mass with improved shear strength. The newly
reinforced soil mass can then provide stability for landslides, cut slopes and deep excavations.
why you need them:
Soil nail walls are used for a number of reasons, including stabilizing slopes and landslides, limiting ground settlement and providing
earth retention systems for deep excavations.
