ABSTRACT:
A method of anchoring elements in rock or the like, an expandable portion thereof being embedded in a borehole; and a cartridge containing binder mixture and having a liquid-permeable but binder mixture-impermeable casing and further being surrounded by a rigidifying member. The cartridge is inserted in the borehole after having been immersed in a binder mixture-activating liquid penetrating its casing, thereby providing a substantially uniform mixture. When inserting the element in the borehole, activated binder mixture is pressed out of the cartridge without any spring effect occurring due to the rigidifying member being destroyed.
