Job calls for 4 course of 8" block with a course of 6" on top. Concrete slab poured inside 6". Problem im having is im left with 2 inches above the slab that my 2 x 6 wall will sit on and im afraid im gonna have a condensation issue on back side of drywall at the bottom. I mean if i insulate the open cells im still gonna have cold spots at all the webs. Its got radiant floor heat will that help keep condesation from forming on the inside of the block. I dunno call me stupid but im having trouble with this little detail.....:blink:

Hey thanks for the great insight there. The problem lied with keeping the plane of the wall so we didnt have to strip 128' of wall to match whatever foam we stuck to the inside of the block. If we filled the top course thats above grade with vermiculite i was concerned the block web would still be a cold transfer condensating on the back of the drywall. Decided to bump the wall in to make the sheathing flush with the outside stick 1/2" aluminum faced insul board to cover block then run drywall over the foam while still filling the web of the block.
