Routuminen
Routuminen is a Finnish term that describes the process of freezing and thawing of soil. This phenomenon is significant in cold climates and occurs when the temperature of the ground drops below freezing point, causing water within the soil to turn into ice. As ice forms, it expands, exerting pressure on the surrounding soil particles and leading to an increase in soil volume. This expansion is known as frost heave.
The extent of routuminen depends on several factors, including the amount of water in the soil, the
When the temperature rises above freezing, the ice within the soil melts. This process, called thawing, can
