As part of this study, a testing program was developed based on an analysis of the operating conditions of pile foundations in Arctic conditions to determine the type of material and manufacturing technology for polymer composite piles. It was shown that the most significant factors are the combined effects of humidity, thermal cycling, air and soil salinity, and UV radiation. Protective coatings minimize changes in properties and surface damage to the polymer composite. It was determined that basalt-fiber reinforced plastic or fiberglass tubular elements manufactured using a wet winding method can be used for the manufacture of bored piles. Based on the conducted research, an analysis of the types and consequences of PCM pile failures in Arctic conditions was conducted. It was determined that the most hazardous areas of an installed PCM pile are the aboveground portion and the section located in the seasonal thaw zone. These results were verified by field tests at the Yakut Scientific Center of the Siberian Branch of the Russian Academy of Sciences.
