The blue numbers are the amount of precipitation in either millimeters (liters per square meter) or inches. The red numbers are the average daily high and low temperatures for each month, and the red bars represent the average daily temperature span for each month. The thin gray line is 0 °C or 32 °F, the point of freezing, for orientation.

Photograph taken 21 March 2010 in Norwich, Vermont. Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).
If the surface of the concrete pour is insulated from the outside temperatures, the heat of hydration will prevent freezing. The American Concrete Institute (ACI) definition of cold weather placement, ACI 306, [129] is: A period when for more than three successive days the average daily air temperature drops below 40 °F (~ 4.5 °C), and

Each white lump marks the top of a deep ground-freezing tap. Cross section of a ground freezing pipe as used in the Big Dig. Ground freezing is a construction technique used in circumstances where soil needs to be stabilized so it will not collapse next to excavations, or to prevent contaminants spilled into soil from being leached away.

Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
