Thaw settlement
Thaw settlement is the gradual sinking or lowering of a building or ground as frozen soil thaws and loses its stiffness. During winter, soil can freeze and harden, supporting structures well. When temperatures rise and the soil thaws, it can become soft and lose strength, causing the ground and any structures on it to shift downward slightly. This process can impact the stability of foundations and structures, making early understanding and planning essential in cold regions to prevent damage or uneven settlement.
