Method and Arrangement for Improving Soil and/or for Lifting Structures
First Claim
1. A method for condensing, filling or replacing soil and/or for lifting structures, the method comprising providing the soil or structure with a hole, arranging into the hole an injection bar and an expansion element provided in connection therewith, and injecting a substance into the expansion element, whereby the substance expands as a consequence of a chemical reaction, so that a force pressing the expansion element against the soil is generated mainly by the chemical reaction.

Abstract
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 injected 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).
