ABSTRACT:
A dispensing apparatus for delivering grout or other material, in either a single column or a plurality of spaced apart columns, is comprised of a body member having a pneumatic chamber with a pair of end caps attached to opposing ends. A piston is adapted to slide within the pneumatic chamber. A discharge nozzle having at least one discharge port is removably attached to one of the end caps. A control system controls fluid flow communication between the pneumatic chamber and the discharge nozzle. A pair of valves are attached to the end of the body member opposite the discharge nozzle end. One of the valves controls fluid flow communication between the pneumatic chamber and a source of pressurized gas while the other valve acts as an air relief valve.
