Soil nail walls were designed by Caltrans to shore up multiple steepened slopes along the 12 freeway in Napa Valley California to reduce the chance of possible slope failure. The aesthetics of these soil nail walls were of high importance to Caltrans and the City of Napa Valley. The walls needed to visually blend well with the environment around it and also be easy on the eyes for passing motorist. Our Napa Granite was chosen to meet these requirements. We finished a total of 201,440 square feet of Napa Granite finish over multiple soil nail walls. We finished the sculpted finish with a dark earth blend staining scheme.
