Abstract: A shotcrete gun having a rotatable multichamber rotor, with a top feed hopper for receiving a dry concrete mixture in a chamber, and a bottom outlet pipe for discharging the dry concret mixture from the chamber. The outlet pipe having a compressed air connector for connection to a compressed air source. The upper surface of the drum rotor adjoins a gasket having one or more openings fixed to a clamping plate. The lower surface of the drum rotor adjoins a gasket which is fixed to a base plate. The hopper and the outlet pipe being spaced such that a chamber which communicates directly with the hopper can be moved so that it no longer communicates with the hopper but communicates with the outlet pipe. The clamping plate has a compressed air connector for blowing the dry mixture out into the outlet pipe, and at least three pressure cylinders in order to press the gasket against the drum rotor. Means are provided for maintaining the pressure in the cylinders proportional to the pressure in the outlet pipe.
