ABSTRACT:
A method of injecting a hardenable mass into cracks in a structure includes drilling a borehole into the structure traversing the cracks. Inserting a tubular member into the borehole with the tubular member having an outside diameter smaller than the diameter of the borehole. Filling the gap between the borehole surface and the tubular member with a hardenable mass forming a seal of the gap at the opening into the borehole. After the seal has hardened, injecting a hardenable mass into the tubular member so that it flows into the borehole and enters into the cracks in the structure.
