Abstract
A method for fabricating concrete structural elements is shown. According to the method, a structural element, such as a sheet of insulating material reinforced with concrete, is vertically oriented and coated with fresh concrete sprayed by a shotcrete gun. This coating is then smoothed and shaped as required by the given application. The method does not require the use of moulds to cast the structural element, whose surface is therefore visible at all times during the course of manufacture. This allows for the repair of imperfections before the concrete has hardened.
