Abstract
In securing an anchor in a borehole in a receiving material, a settable hydraulic dowel compound is introduced into the borehole either before, during or after the placement of the anchor member. The dowel compound includes an expandable component. The diameters of the borehole and the anchor member are selected so that an annular gap extends around the anchor member with the gap having a maximum area of 200 mm.sup.2. The expandable component ensures an increase in the volume of the dowel component above the initial volume in a free expansion procedure.
