The article describes the diagnostic procedures and methods used for monitoring of exploration gallery lining exposed to action of an aggressive bottom environment. It concerns the so-called control galleries, which became in the framework of tunnel building the part of the primary tunnel lining. The galleries pass through very complex terrain in light of morphological geology. The effect of this fact is that the galleries are in their different parts exposed to attacks of water, the aggressiveness of which towards reinforced concrete structures is significantly variable. The realised research showed that it is necessary to classify the water, which penetrates through the gallery lining in some localities as moderately aggressive towards reinforced concrete.The objective was to assess the condition of reinforced concrete gallery lining and mainly the further durability prediction of such constructions in given environment.
