The invention provides a process for the protection of active reinforcements embedded in a concrete mass against the effects of oxidation, said reinforcements being possibly in the form of a bunch of cables or strands arranged in a sheath, providing also the possibility to detect imperfections of the injection grout such as voids or porosity, wherein at least one channel is first drilled in the concrete mass opening in front of the reinforcements which has to be protected, whereafter a corrosion inhibiting solution is injected into the said channel while applying a high power pulsating wave to the said solution to make it penetrate and each channel is occluded.
