Technique: Soil Nail & Shotcrete Walls

Soil Nail & Shotcrete Walls

Earth retention system consisting of near horizontal steel bar reinforced elements that are drilled and grouted into the excavation face as excavation advances to create a reinforced soil or rock mass. As the elements are installed in a horizontal lift, a wire-mesh reinforced shotcrete face is constructed to span between soil nails. The process is repeated in consecutive, near-vertical lifts (typically 5-feet) until the designed wall depth is achieved.
