Abstract
The paper dwells on the influence of confined waters of the Nizhnekotlinsk aquifer, creating favorable conditions for microbiota development and its aggressive impact on construction materials. The main destruction forms have been classified basing on the research carried out in underground workings. Composition of water extracts prepared from destroyed concrete and various types of new growth have been investigated. A conclusion is drawn about the role of biocorrosion in destruction of tubing and a damp-proof lining based on the results of experimental research.
