heave

Such soil is referred to as "frost heave susceptible." Two common criteria for susceptibility are more than 10% of soil particles being finer than 0.075 mm or more than 3% of particles being finer than 0.020 mm.

Visible vertical displacement of the ground surface or effects on pavement would be consistent with the occurrence of frost heave.

The primary structural integrity effect to pipeline systems as a result of frost heave is excessive longitudinal or bending stress due to the displacement strain imposed by the earth movement.

Unfortunately, upward frost heave can be a concern if the ground freezes against the foundation.

With many rubble foundations, we dodge the adfreezing bullet and lateral frost heave forces because the rubble foundation wall is a pretty good drainage medium (Figure 9).

Soils that contain coarse particles of gravel and sand drain well and won't usually heave, because they don't collect and hold enough water to form frost lenses.

Even frost-susceptible soil usually won't heave if you provide good drainage (assuming the water table is far enough underground).
