Mulch after several hard frosts in late fall to minimize frost heaving. Cut back the foliage to the ground in early spring before new growth begins, but there is no rush.
This depth is required to prevent frost heaving from disturbing the foundation, and it amounted to moving 2 cubic yards (about 8,000 pounds) of dirt.
Konrad and Lemieux [27, 28] thinks that when the content of fine-grained soil in coarse-grained soil is less than 7%, the frost heaving of coarse-grained soil is relatively small, but the amount of water supplement is very obvious, and the frost-heaving ratio of 1% is the standard to distinguish frost heave sensitivity of coarse-grained soil by laboratory freezing tests.
When the soil temperature is lower than the freezing temperature ([[alpha].sub.T] = [alpha][[theta].sub.i]), a is the frost heaving coefficient of the soil ([degrees][C.sup.-1]).
This is the natural shape of the trees they make them from, but the tapered shape also helps keep them seated in the face of frost heaving. Posts that are improperly buried can work their way out of the ground, but if we sink our posts with the fat end down, the tapered shape will actually help keep the post from rising over the years of frost-thaw cycling.

In particular, its tests examined how insulating the pipe or placing non-frost-susceptible soil under the pipe could deter frost heaving.
In the study, the critical issues associated with declining pipeline throughput are: frost heaving of belowground pipeline sections; water settlement in the TAPS stream; ice formation in the pipeline, deposition of wax the interior pipeline wall; and the possibility of high viscosity oils delivered to TAPS in the future.
Frost heaving is due to the growth of ice crystals not due to a change in the volume of frozen water.
Controlling water in its various roles can reduce the impact of such landscape problems as drought, frost heaving, erosion, settling, and ponding.
