A hole (6) is provided in soil or a structure, and an injection bar (1) having a fillable expansion element (2) in connection therewith is arranged into the hole. A substance which expands as a consequence of a chemical reaction is in- jected into the expansion element (2). The expansion element (2) filled with the reacted substance condenses, fills or replaces surrounding soil or lifts as well as stabilizes ground-based structures. A force pressing the expansion element (2) against the soil is generated by the chemical reaction which expands the substance injected into the expansion element (2).
