ABSTRACT:
A method of and an adhesive cartridge for securing an anchor or the like in a bore hole or the like. The cartridge comprises an outer tube and an inner tube within this outer tube. Between the inner and outer tube is a mass of synthetic-resin material and filler. The inner tube is filled with a hardener capable of reacting with the synthetic-resin to form a mass capable of holding the rock anchor or the like in the borehole. At least the outer tube is made of an elastomeric polymer with which is mixed a filler that renders the outer tube completely opaque. The inner tube may also be extruded simultaneously with the outer tube of the same synthetic-resin material. It is also possible otherwise to partition the interiors of the outer tube, or to provide the one component in the outer tube directly in contact with the other component but unmixed therewith.
