Abstract In areas of intensive construction on the Arctic coast, river valleys of the Republic of Sakha (Yakutia) non-freezing taliks with a high concentration of pore solution (cryopegs) are found in the strata of permafrost soils. N. P. Anisimova made a great contribution to the study of the cryopegsformation in the cryolithozone [1]. For solutions of any composition, it is established [2] that there is a general dependence of the relative freezing temperature on the relative concentration of the solution. It has also been established that the effect of dissolved salts is additive. The freezing temperature of the solution in the pores of dispersed media is affected, in addition to the concentration and composition of the solution the adsorption capacity of the material in relation to the components of the solution.
