Abstract (en)
[origin: CA3224435A1] A method for manufacturing an element (E) in a ground (S) comprising a drilling step during which a grout (F) comprising a first composition is introduced and after the drilling step, at least one grout activation cycle is performed during which at least part of the grout is pumped; a second composition (C) configured to activate the grout by reacting with the first composition in order to initiate the hardening of said grout is added to the pumped grout; then the activated grout is introduced into the excavation (H); and after said at least one grout activation cycle, the activated grout is allowed to harden in order to form the element in the ground.
