Foundation/Frost line
Foundation/Frost line
(OP)
I am building a new home. The home has decorative brick wing walls at each corner supported by concrete foundation walls. One of the walls was only poured 36" deep. The frost line in my area is 42" deep. Will I have a problem with frost heave? What can I do to extend the wall below the frost line? The foundation wall sits on very stiff to hard clay. Thank you

Insulation is only effective on the outside of the foundation. You need to keep frost from getting under the edge of the foundation. You could potentially use it, but I think it would be a waste of cash and it would be relatively time consuming.

This would particularly applicable if it's not possible to raise grades 6 inches. However, if it's possible to raise grades, I think the use of soil would be more cost effective.
