A few years ago I ran across this website that has a rather unique ICF block. Instead of just dumping cement in between two foam walls, this block has circular channels that literally create a pillar within the blocks. Like 5 or 6 per 4ft block.
I only recall that it was called "Kiva" or something similar. Thanks to google's brilliant searching techniques, I get thousands of hits on stuff not even related to what I want.
Anyone have the link to the actual website or something similar?
