Soil Nail Walls

Soil nails are used when soil slopes, excavations or retaining walls need reinforcement. Typically, this is done by using steel reinforcement bars. First, the bars are installed in a pre-drilled hole. Then, they are grouted or drilled and grouted into place simultaneously. Soil nail walls are normally installed un-tensioned and at a slight downward inclination. At the surface, isolated soil nail heads or a rigid or flexible face (often times shotcrete) may be used.
