The planning and execution of work on preconstruction improvement of the construction characteristics of perennially and seasonally frozen soils which are to be used as bases for buildings and structures are presented. Instructions for carrying out foundation excavations, for preventing frost heaving of soils and heaving of foundations under winter freezing conditions are included. Thawing of seasonally and perennially frozen soils with the aid of electric power and chemical agents when the temperature is both above and below zero, and also compaction and heave stabilization of such soils are discussed.
