Abstract (en)
[origin: WO2015078722A1] The invention relates to a method for restoring a collapsing structure that has at least one crack (22) resulting from the collapsing. A reinforcing substance is injected into the foundation of the structure at said crack (22) in a main bore hole (50). According to the invention, simultaneously with the injection, a curve indicative of the joining edges (24, 26) of the crack (22) is traced, the injection being stopped when an abrupt decrease in the absolute value of the slope is detected in the curve.
