An improved hardenable inorganic grouting composition cartridge comprising: (1) cartridge filler ingredients comprising, (a) a dry inorganic cement powder, and (b) liquid containing capsules, and wherein the liquid is reactive with the inorganic cement, and wherein the capsules are pressure sensitive and capable of being progressively ruptured by the force of the anchor element, (2) an elongated flexible tubular casing containing the filler ingredients, and (3) a reinforcing member, preferably a flexible one, which adds lengthwise rigidity to the cartridge casing. The grouting composition cartridge of this invention is injected into a hole in a support structure. An anchor element is then introduced into the hole containing the grouting composition cartridge. The grouting composition is released from the casing thereby forming a hardened grout around the anchor element. This invention also includes methods of manufacture and usage of the improved cartridge.

A cartridge for grouting an anchor element in an elongated hole of a support structure, comprising (1) an elongated tubular casing fabricated of a frangible material capable of being punctured and shredded by an anchor element thrust into said cartridge and having a diameter between enclosed ends sufficient to enable said cartridge to be introduced into said hole; (2) a substantially homogeneous mixture of cartridge filler ingredients comprising (a) a dry hydraulic cement powder, and (b) water-containing capsules substantially uniformly dispersed in said cement powder that fills the interior of said tubular casing between said enclosed ends; and (3) a flexible reinforcing member fixedly attached to said tubular casing to thereby add lengthwise rigidity to said casing; and wherein said capsules have inert, frangible shells enclosing droplets of water, and wherein said capsules are pressure sensitive and are capable of being progressively ruptured by the force of said anchor element being thrust into said cartridge when said cartridge is positioned in said hole to thereby dispense the water substantially uniformly throughout said cement powder to enable said water and said cement powder to thoroughly interact to form a flowable cement paste in contact with the hole wall and said anchor element, which when solidified forms a grout about said anchor element to secure said anchor element to said support structure.
