The invention makes it possible inter alia to obtain a passive dry store. Receiving cavities for storage are formed by drilled vertical holes 6 which extend to a level 10 lying above an underlying drainage and ventilation zone 11. The hydraulic barrier 7, which is displaced laterally in relation to the storage boreholes 6, and laterally located ventilation holes 12 are connected to the underlying drainage and ventilation zone 9.
