In my 19 years of manufacturing and distributing Stucco and EIFS I thought I had seen it all.  These pictures are taken from a school which has EIFS on it and the rocks that are embedded in it were used like "throwing stars".  The EPS foam is 1" thick and has high impact mesh ran 8' up the wall and then standard 4 1/2" oz mesh over the entire wall.  The rock did penetrate through the high impact stucco but the kids found it easier to stick them above that area.  This would have been a better job for the use of traditional stucco. .
