A compound anchor to affix an anchor shank in a borehole, comprising a glass cartridge (12) which can be inserted into the borehole and which receives both cement or a dry mortar and an inside container encasing water. A sealing cap (14) is present at the borehole entry and can be pierced by the anchor shank (15) and will seal the borehole at least until the binder hardens. The inside container (22) consists of container parts (26) distributed over the length of the cartridge (12) and individually destroyed as the anchor shank (15) advances into the borehole, whereby the dry mortar shall be evenly soaked with the liquid component in all depth zones of the cartridge and shall be mixed with the cartridge and inside-container splinters (FIG. 1 ).

A compound anchor for securing an anchor shank in a borehole, comprising: a) an outer cartridge closed at its front end and adapted to be received in a borehole; b) said cartridge being made of a brittle material and filled with a powder component of an inorganic, hardenable binder; c) a brittle inner container disposed inside said cartridge and filled with water to form a liquid component of the hardenable binder; d) a covering element for closing said cartridge at its rear end; e) said cartridge and said inner container are adapted to be destroyed and turned into splinters when the anchor shank is forced through said covering element, thereby releasing the components into the borehole and mixing the splinters therewith; f) said covering element being an elastic sealing cap having a lid adapted to be pierced by the anchor shank and thereby provide a seal around the anchor shank; g) said sealing cap having an axially disposed outer rim adapted to form a seal between the borehole wall and the outside of said cartridge; and h) said inner container including portions delimited against each other and distributed over the length of said cartridge such that said portions are sequentially destroyed when the anchor shank is being forced in, thereby gradually releasing the included water to the powder component surrounding said inner container portions so that the powder component is uniformly mixed with water in all depth of the borehole.
