The paper presents the experience of the long-term observations on frosty heaving, the construction experience and the state of the structures during 38-40 years of maintenance of the buildings on bearing piles in extremely upheaval soils. The paper describes the experiment of using complex anti-heaving sheath from chemically treated soil as an anti-heaving stabilization. It also presents an example of uneven upheaval deformations of unloaded bearing piles, caused by the discordant bedding of the clayey soil. The paper analyzes the causes of uneven deformations of frosty heaving, the factors influencing the migration and water accumulation, the peculiarities of cryogenic structure formation on the boundary of the interaction of the treated and untreated soils.
