When a footer is used in conjunction with a basement or crawlspace, a drain is certainly required. In the case of a footer used in conjunction with a frost wall and slab (for a garage for example) is a drain required on the footer? In my situation, putting the drain on the footer is not the problem however running it to daylight presents several issues. Curious as to what function the drain would serve in the case of a footer set at 42" below grade and a slab foundation on grade.
Any thoughts would be appreciated.
