It is found in the pores and cavities of the soil, especially in the near-surface area of ​​the permafrost and in the thawing soil above . In many cases, it represents the “cement” that holds the soil particles together.

The pore ice only includes the bottom ice, which can absorb the pore volume in the liquid state. Contains the base further "excess" ice (engl. Excess ice ) caused during this thawing a reduction of the ground. Such additional ice is typically segregated ice .
