Minimum Soil Cover
Minimum Soil Cover
(OP)
What is the minimum soil cover that you need to be on top of an exterior footing. The frost depth is 3'-6" and the footing is 4' deep. I always thought that the footing had to be at least 12" below grade. I just want to be avoid extra excavation costs.
There is no uplift on the footing so I don't need the soil weight for that particular purpose.

RE: Minimum Soil Cover
Are you asking minimum depth to bottom of footing, in lieu of or at variance with code, that will be adequate? Since the minimum depth is usually based on avoiding damage due to frost/frozen ground, the minimum depth depends on thermal aspects (whether building is heated and extent of foundation insulation), and soil and groundwater conditions.

As for me, I don't give a rip.
