Frost lines are typically determined by the moisture and soil content, as well as the average temperatures in the region. Testing the exact depth relies on instruments known as frost tubes that consist of a small hollow tube that is inserted into a drilled hole in the frozen ground.

Does footing 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.

How far down do you dig for deck posts?

Digging Your Footings On the safe side, dig your footings at least 48 inches deep, or check with your local code enforcement. Your deck will not pass inspection with inadequate footings and the posts can be forced up by frost when the ground freezes, known as “heaving” which can destroy it.

What is the frost line in astronomy?

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 ground freeze line?

The frost line is simply the deepest point in the ground to which ground water will freeze. It’s also referred to as the frost depth. When water changes from liquid to solid, it expands 9% in volume. This resulted frost heave can be detrimental to footings and foundations.

If the map isn’t accurate enough for you. Check your frost line by zip code or address using this map from the National Weather Service. As we mentioned before, make sure you check with your local building codes before you start digging.

Should water pipes be above or below the frost line?

Water pipes should always be set below a frost line to prevent them from freezing in the winter. It’s also important that the footings for a building or a deck be well below the frost line so the posts don’t shift as the ground freezes and thaws. Check your local building codes to determine the proper depth past a frost line a footing should sit.
