The injection gun has a feed funnel (12) for dry concrete mixture; and outlet socket with compressed air connection; and between them a motor-driven multi-chamber drum rotor (4). The rotor engages via a top sealing plate (11) on a top assembly plate (10), and via lower sealing plate (9); on a base plate (1). At least one rotor chamber (6) is constantly connected to the funnel, but a different chamber (5) is connected to the outlet socket. The sealing plates are pressed against the rotor, by three pressure cylinders (18). The pressure of these cylinders is proportioned to the pressure in the chamber, which is connected to the outlet socket. The pressure is maintained on a proportional level by pneumatic/hydraulic pressure intensifier.
