New Question: (12-11-2009) See Post # 7
I plan on pouring a slab foundation for an 8x12' shed I'll be erecting soon. The ground in the area we intend to put the shed appears well drained. The HO is really concerned about frost heave - although he admits to never having had any frost heave problems before; nevertheless, this is Kentucky & we do get freezing weather...
My plan was to dig about 7 inches down, back fill with gravel compacted to 4 inches & pour a slab 4 inches thick (thicker at the edges). I figured frost heave likely wasn't a problem, given the size of the slab & condition of the ground - but wanted to ask before I got started anyway...
Am I right thinking that frost heave isn't a concern for this structure? if not, would using concrete tubes & pouring 24" footers at the corners & at about 6' down along the edges of the length be sufficient?
(While I've helped pour sidewalks, etc. - this is my first foundation as the contractor where I've got to do the planning as well as the execution!)
