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.
Silty and loamy types of soils may be susceptible to frost heave while clay, clean sand and gravel are not.
Lines buried below the frost line are less susceptible to the effect of frost heave since the earth movement typically occurs above the frost line.
The ability of a pipeline to with-stand high longitudinal stress or strain may affect its likelihood for failure due to frost heave.
Even frost-susceptible soil usually won't heave if you provide good drainage (assuming the water table is far enough underground).
People who live in the Southern Gulf States and on the Pacific Coast, where frost rarely penetrates the soil more than an inch or two, don't need to worry about frost heaves.
To prevent frost heaves, the easiest and least costly solution is to plan in advance for good drainage away from walks, patios, garages, decks and other floating structures (Fig.
Solidly packed soil, mounded at the top, will keep water from saturating the soil around the footing and causing potential heaves.
Since the calculations indicate that frost heave
produces more thrust when it occurs in coarser substances, Hallet suggests using finer-grained concrete to build heave
Eventually, Wolff wants ownership of the Frost Heaves
to filter into a community trust, and he plans to take advantage of the local businesses (Ben and Jerry's, for one) on the concessions.
In addition to its product for equine heaves
, the company has developed therapeutics for feline leukemia, canine mast cell tumors and cardiomyopathy.
