We witness many interesting processes during the construction of any given project. Recently we were on site as the crew of Austin Custom Pools shot the gunite for a privacy wall postioned next to the new swimming pool at the Clark House. Typically used to form the walls of pools, shotcrete (Gunite is a proprietary term) is a process of spraying a very dry concrete mix through a hose at high velocity. A nozzleman controls the addition of water as it is sprayed in place. The application is fast, and the compressive strength of cured shotcrete is extremely high.

Shotcrete process complete. A more precise shape (but still rough) is achieved by hand-shaping the concrete while still wet. This wall will receive a finish application of exterior plaster.
