The process of application of concrete and mortar by shotcrete was invented in the US at the beginning of the 20th century. In 1907, the American Carl Akeley used this method to repair the facade of the Columbian Museum in Chicago (the old Palace of Fine Arts of the World’s Columbian Exhibition). In 1911, Carl Akeley received a patent for the "cement gun". At present, the shotcrete is used both for new construction and repair / rehabilitation of old buildings. The aim of this study was to present, analyse and synthesise the current references existing in the literature, presenting the two currently used methods for obtaining shotcrete: dry and wet.
