Calculating frost penetration in soils

Player
Short video description
Burn Placing foundation footings below the frost line in frost susceptible soil does not necessarily ensure that a structure will be protected from damage from frost heaving. Movements in the soil resulting from ice lens growth can be transmitted to the structure if soil freezes to the foundation walls or supporting columns. The process is called adfreezing. This Digest is intended to draw attention to the problem of foundation heave resulting from adfreezing for such structures as attached garages and carports, basement garages, separate garages, unheated warehouses, cottages and mechanical and electrical service units sensitive to differential movements. The change of soil water to ice when the ground freezes greatly increases the strength of soil, but this same strengthening process is also responsible for the strong bond adfreezing that may develop between the foundation unit and the soil.

CBD Adfreezing and Frost Heaving of Foundations - NRC-IRC

Historical understanding of frost heaving[ edit ] Ice lens formation resulting in frost heave in cold climates. Ice is unusual among compounds because it increases in molar volume from its liquid state, water. Most compounds decrease in volume when changing phase from liquid to solid. Taber showed that the vertical displacement of soil in frost heaving can be significantly greater than that due to molar volume expansion. He showed that other liquids, such as benzene , which contracts when it freezes, also produce frost heave. His experiments further demonstrated the development of ice lenses inside columns of soil that were frozen by cooling the upper surface only, thereby establishing a temperature gradient.
