Footing Cover

[scottiesei]

Gentleman,
What would be the minimum depth for the footing of a wall? Could it be 8"? Footing is directly cast againist earth. I am looking at ACI318 req. of 6" of cover ABOVE reinforcing. So if I use a #5 bar, with the req. 3" of cover on the bottom and 6" on the top, I find 8" impossible. Am I missing something?
Thanks!

Sorry, I think this is another regional thing What is a "chair block"?

Looks like a "L" somewhat. The top half of the inside face shell is removed so the slab pours right into the wall.

See page 55, block T062. also great for running a #5 continuous for frame construction...

Thanks Scott.

For that condition, I think I would lap the vapor barrier into the block ~2"
