Abstract
It is very important at the present time in conditions of multilevel developing Saint-Petersburg to have an opportunity of prediction and diagnostics exogenous processes during the designing, construction, maintenance and buildings reconstruction. It is shown the necessity of taking into consideration the man-caused factors as chemical, microbial and temperature pollution of geological environment, which is exerting influence on transformation of soils condition under the buildings foundation. The principal concern is attended to the pollution by domestic sewage influencing on moraine and lacustrine loam which is used as a base layers for pile foundations and natural bed for continuous footing of 18-19 centuries buildings. It is underlined the role of soils corrosion activity and the profound effect of biocorrosion processes in lining material destruction.
