Avg. Max. Frost Depth in South Carolina Avg. Max. Frost Depth in South Carolina TBell47 (Structural) (OP) 2 Nov 05 11:28 Can anyone tell me the (average) maximum frost depth in the state of South Carolina?Thank you.T-Bell47 RE: Avg. Max. Frost Depth in South Carolina blackwed (Electrical) 2 Nov 05 12:39 I don't have direct knowledge from an engineering standpoint, but having lived here, up-state to coast, for 54 years, I don't think it gets cold enough long enough in any part of the state to actually freeze the ground. Maybe in the mountains? I seriously doubt it in the midlands and surely not along the coast.DB deja moo: I've heard that BS before. RE: Avg. Max.

See Table R301.2 (1), 2000 IRC - Climatic and Geographic Design Criteria. Lists SC as none, but, contact the local building department for local conditions.CheersBoo1 RE: Avg. Max. Frost Depth in South Carolina SlideRuleEra (Structural) 2 Nov 05 17:30 Concur with blackwed, however assuming a frost depth of 6 inches anywhere in South Carolina is a typical, very conservative assumption.The state currently uses IBC 2003. If you are considering footing or foundations, frost depth is not really an issue. IBC Section 1805.2, Depth of Footings, states "The minimum depth of footings below the undisturbed ground surface shall be 12 inches" www.SlideRuleEra.net RE: Avg. Max. Frost Depth in South Carolina SCGeo (Geotechnical) 3 Nov 05 08:53 TBell, I live and work in the upstate of sc, and I agree with SlideRuleEra. Its unlikely that the frost depth penetrates 6 inches anywhere except possibly in the mountains. As was pointed out in the IBC 2003, the depth required for seismic stability anywhere in sc extends well below the frost line. RE: Avg. Max.
