Soil Nail and Shotcrete Retention
Soil nails are drilled and grouted steel elements that are installed to reinforce existing soil as it is excavated in lifts. Soil nail spacing is controlled by the allowable depth of each lift, which is driven by soil conditions. After soil nails are installed at each lift a drainage system and reinforced shotcrete facing are installed over the nails. This process continues until the desired excavation depth is achieved.
