Soil Nail face Options
While we love soil nail walls and beauty is in the eye of the beholder, plain as-shot shotcrete doesn’t always look the best. The plates are typically exposed and galvanized or are covered with a mound of shotcrete. These two approaches are the least costly. But if you want an upgraded look for your permanent soil nail wall, there are a lot of options out there.

One option is to screed the shotcrete. We pull wires and place shotcrete. We then use trowel boards to cut the shotcrete face back to the wire, leaving a plumb faces with excellent horizontal alignment.

One downside to exposed shotcrete, which can happen with other types of concrete facing, is calcification stains should ground water seep through the face rather than following the installed drainage and weep holes.

Segmental Block Veneer
One very popular option is to place a segmental block veneer. The best thing about this option is the “cut” soil nail wall face will match the “fill” segmental block (MSE) walls.

Architectural Shotcrete Face
My favorite soil nail face is architectural shotcrete. In particular, we like the geologic face. The faux rock face is very attractive and since it looks great with some ins and outs, there is less pressure to hold a perfect line with the soil nail wall. We strongly recommend our favorite partner for architectural shotcrete, Boulderscape.
