Frost protection for foundations on bedrock
Frost protection for foundations on bedrock
(OP)
Do spread footing foundations which bear directly on bedrock (unweathered) need to be extended down to frost depth? Specifically, we have a case where bedrock is, say 24" below grade, and minimum frost depth of 42" below grade. Is it necessary to excavate the rock to achieve the 42"?

However, it seems logical to me that frost is not an issue in this case.
