A rapid and flexible earth retention solution, soil nailing can be used as both a remedial measure, to make unstable soil slopes safe, and as a top-down construction technique, whereby existing or new soil slopes can be engineered at steeper inclines.

Soil nailing is used primarily for excavation support or slope stabilization.  This process involves the installation of closely spaced soil nails drilled near horizontal and the application of a facing material such as reinforced shotcrete or structural mesh.  The soil nails themselves tend to be small in diameter, typically 4″ to 6″, and consist of a center reinforcing bar surrounded by grout.  Soil nail spacing usually ranges from 4′ to 6′ on center vertically and horizontally with the top row of soil nails generally being placed in the upper two feet of the excavation or slope. 

From a design standpoint, soil nailing is a passive system attempting to place enough anchorage into the adjacent soil so it acts as a “reinforced block” to resist overturning.  The load demand on each nail tends to be fairly low as they are intended to act as a group.  

In the case of excavation support, the facing is usually designed to take little load but more so tie the system together.  In the case of slope stabilization, the facing may be designed to take more load and the nails may be post tensioned.

The soil nails we install are generally steel bar type, grouted into near-horizontal pre-drilled holes. We apply reinforced shotcrete or precast concrete facing panels, held in place by bearing plates bolted to the soil nail head.

The tensioned soil nails effectively bind the slope together, creating a solid retaining structure in far less time, and at a much lower cost, than a traditional block-built retaining wall.
