Zusammenfassung:A rock anchor includes an elongate tubular body which extends between a first end and an opposing second end and a cartridge contains a multi-component adhesive system in the tubular body. The cartridge has a rigid tubular housing within which at least one compartment is defined, and in which is contained an adhesive component of the system. The at least one compartment yields to volumetrically reduce under fluid pressure created by a fluid input into the housing, to thereby extrude the adhesive components.
