Frost Depth Alabama

Frost Depth Alabama

Frost Depth Alabama

(OP)
Anyone know what the frost depth is in middle to lower part of Alabama near Mississippi? This is in an area where there is no local jurisdiction.

RE: Frost Depth Alabama

The 1999 Standard Building Code shows the entire state's frost penetration as 2 inches.

I will keep looking for another reference.

RE: Frost Depth Alabama

Two good references are the local building inspector and the local grave digger.

RE: Frost Depth Alabama

12" conservative max frost depth. A typical spread footing at the perimeter of the building will have 12" of cover and be 12" thick...well below frost depth. I typically keep 12" of cover even in Florida.  

RE: Frost Depth Alabama

Wow, off the topic a bit, but I didn't know it got cold enough long enough for the soil to actually freeze in AL or FL.  More than a fraction of an inch or so that is.

RE: Frost Depth Alabama

Is this a political question?

Call ANY code authority in Alabama...specifically northern AL - like Huntsville.  Probably about 12''

RE: Frost Depth Alabama

No frost depth in Mobile.
