An injection cartridge contains a number of components in separate chambers. To use the cartridge, the chambers are brought into communication and the components mixed to form a compound such as an adhesive which can then be injected into a hole. The cartridge has a rigid housing which incorporates a movable mixing rod for mixing the components together, a displaceable injection opening and a piston which can be moved along the housing to extrude the mixed compound out through the injection opening.
