Are All Concrete Swimming Pools Gunite?
Gunite is a term used to describe the material that is produced by the dry gun shotcrete method. Gunite was invented in the early 1900’s by Carl Akeley. Gunite is produced by forcing a dry sand and cement mixture through a hose with air pressure, Water is then injected into the mix at the end of the hose through a nozzle. Gunite was the original term coined by Akeley, trademarked in 1909. Carl was granted a patent for his “cement gun” and “gunite” in 1911. Recognizing the market for the new invention, S.W. Traylor, a businessman from Allentown, Pennsylvania bought the rights to build the machines and do the “Gunite” construction work and formed the Cement Gun Company of Allentown, PA in 1915. “Gunite” then became a trademark of the Allentown Equipment Company. The American Railway Engineering Association coined the term “Shotcrete” in the 1930’s to describe the process used to produce the trade name material “Gunite”. This term was also later adopted by the American Concrete Institute.
