Re: Footing bottoms relative to the frost line

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Albert,

Technically speaking, published frost depths are minimum depths for the
bottom of footings.  However, in our practice we've always applied this to
the top of footings, thus providing us that warm and cozy feeling.
