We Installed a Soil Nail Retaining Wall for This Project:

To keep property impacts to a minimum the City is used soil nails in the construction of the retaining wall.

The Soil Nail Process:

A cut is made into the existing slope with an excavator.
The soil nails are installed by a drill rig. The soil nail spacing and length are determined by the specialty contractor’s engineer to stay within the right of way.
Inside the soil nail drill holes, reinforced steel bars are placed and grout is pumped from the bottom of the hole to the top of the hole.
Welded wire fabric is placed vertically and then shotcrete is installed. (Shotcrete is a method of applying concrete at high velocity out of a hose nozzle.)
A steel plate and nut is added at the face, to connect the shotcrete to the soil nails.
For the this project, a cast in place concrete face will be installed directly in front of the shotcrete, providing a final uniform wall face.
