The paper describes a novel slab-on-grade foundation (floating foundation) which simultaneously performs three functions: transferring load of structures into the soils; reducing the permafrost temperature at the base of structures, increasing thereby the bearing capacity of soils they sit upon; and maintaining the required positive air temperature in the ground floor of the structure. These are achieved by introducing a heat pump into the foundation design. The considered foundation has significant advantages over the pile foundations widely applicable in the Arctic and provides for: independence from climatic conditions; low capital expenditures; multiple use.
