How far down is the frost line?

36 to 48 inches
Whereas the average depth of frost for our region is between 15 and 20 inches, the established depth frost line varies from 36 to 48 inches. So, the frost line is a “safe” distance beneath the surface of the ground where soil and anything layed within it will not be affected by freezing temperatures.

Where does the frost line start?

In astronomy or planetary science, the frost line, also known as the snow line or ice line, is the particular distance in the solar nebula from the central protostar where it is cold enough for volatile compounds such as water, ammonia, methane, carbon dioxide, and carbon monoxide to condense into solid ice grains.

What is the frost line in a geographical area?

The frost line—also known as frost depth or freezing depth—is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources.

What happens if you build above the frost line?

Anything above the frost line will heave from ice. Ice expands just below freezing. If your pylons are too shallow then your house will shift and crack and generally become very unsafe.

Do fence posts need to go below frost line?

All fence posts should be cemented in the ground below frost level. Check your local frost level and dig deeper by at least 6″.

Does frost penetrate concrete?

Frost heave can wreak havoc on concrete driveways, sidewalks, and patios around your home. As the frost within the soil thaws and melts, the concrete can settle back towards its original position; however, it may remain raised if uneven base material develops beneath the concrete or if sufficient sized cracks develop.

Does frost come up or down?

and neither of them rises out of the ground or falls down from the sky. Both dew and frost are formed directly from the air when temperature and moisture conditions are dust right.

Where is the Frost Line in Maryland? In Maryland the frost line depth is thirty inches. This means that at thirty inches and below underground water will no longer freeze during extremely cold temperatures.

Do footers need to be below frost line?

Depth of Footings Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected.

What happens if footings are not below frost line?

If the footing does not extend below the frost line, the footing will heave as the ground freezes and thaws.

What is the frost line depth for New Jersey?

According to the Corps of Engineers, the 3′ depth line runs east-west through the middle of New Jersey. More for the north half. Code frost figures are based on the coldest weather (greatest penetration) over a long period of time since it only takes one cold year in the life of a structure to cause severe damage.

How deep is the frost line?

The frost line depth varies by geographical location, but frost lines in the contiguous United States range from 6 inches to 6 feet. Local government building officials can provide the frost line depth in a specific location.
