Exterior stone veneer & Rigid insulation

[DoubleStud]

I am working with an architect where he wants to put 2" rigid insulation on the exterior face of the concrete basement wall. Then above that, we will have stick framed wall with ZIP-R system (1" insulation). So the face of the plywood Zip-R system will stick out 1.5" from the face of the concrete. Then at the concrete we have that 2" rigid insulation. How would you support the stone veneer on the exterior wall? Would you just stack CMU right in front of the 2" rigid insulation? The CMU will stack about 10 ft tall. Then put the stone veneer on top of it? How would you do it?

If I am reading your post correctly, the top of concrete wall should be about 6" or more above the ground. So, the stone would have to extend from there up. How much air gap is required between the stone and ZIP-R?

I guess you did not build a exterior brick ledge below grade so you must extend the stone support to the footing. Is that correct?

That is correct. All the way to the footing is what I am thinking.

The zip R system and the rigid foam makes the stone veneer too far away from face of the concrete. Probably a bad idea to use steel angle

I have typically seen builder block—essentially a type of CMU—used from the footing up to the point where the stone veneer is supported. In most cases, I recommend one of two options: either blocks or a steel angle. However, given the distance of the stone veneer from the structural elements, as noted in this discussion, the block option appears to be the most appropriate solution.

Just dry stack the CMU and backfill?
