Storage containers (12) holding hazardous material are stacked in a drilled shaft (11) of a diameter slightly larger than the transverse dimension of the storage containers. Initially, a base plug (13) is lowered to the bottom of the shaft (11) and anchored there by means of a setting grouting compound introduced into a clearance space around the base plug. One end of a plurality of cables (15) long enough to extend from the bottom of the shaft to the upper end of the shaft are attached at anchoring points distributed around the periphery of the base plug (13). The storage containers are then successively lowered into the shaft within the space encircled by the cables (15) and stacked in the shaft. The stacking is discontinued well below the upper end of the shaft (11) to provide space for a backfill sealing the shaft.
