The operation of enterprises in the industrial sector, especially in the chemical, metallurgical, and food industries, is closely connected with the use or storage of chemicals. These substances very often, due to various violations, get into the environment, polluting not only the atmosphere but also the ground directly under buildings and structures.

Pollution and deterioration of environmental structures due to the uncontrolled accumulation of various industrial wastes is a great danger. In this regard, in modern conditions, along with the elimination of sources of pollution, it is necessary to develop new methods and technologies for localization of pollution. Currently, the urgent problem of the construction industry is the reconstruction of buildings and structures, the ground bases of which were contaminated with industrial effluents.

The problem is that industrial effluents, getting into the soil of the bases, lead to such a phenomenon as «chemical swelling». This phenomenon leads to unacceptable deformations of the bases, destruction of the bases and superfoundary designs.

Physico-chemical methods are promising in this direction. The accumulated experience of application of various construction technologies for stabilization of soil bases, shows that chemical fixing of soils is rather reliable, and in some cases and the only possible means for strengthening of weak and chemically active soils of bases.

The problem of increasing the efficiency of the method of improving the construction and environmental properties of soils contaminated with acidic industrial effluents, which include solutions of peracetic acid, is solved. The limit criteria for formulations are obtained, which allow to obtain reliable fixing of soils contaminated with solutions of peracetic acid.

The presented results allow the most effective and high-quality consolidation of soils contaminated with solutions of peracetic acid, taking into account the environmental side of the issue.
