Setting the first course
Commonly used methods
Method 1: Dry set: Pour level footer/slab with dowels and shim/shave first course as needed
Method 2: Wet set: Set forms in the web footer/slab to a string line, insert dowels in wet concrete

We have found that using plastic ties between blocks on the first course helps to keep block in line and makes the second course work go faster. The plastic ties are used to connect each end of the block to the next block by wrapping it around the closet web. We have used this technique on Blue Maxx, Eco and Formtech. In the case of Eco Block we reverse the second connector so that when you tighten the tie the connector does not pop off. I am sure this process can be used with most any block. The ties can be purchased at almost any building supply store like Home Depot etc. You can also buy a plastic tie puller similar to the Yankee used with wire ties.

I put the first block down at the highest point of the footing and shim as needed to lay first course level. That way I don't have to do any shaving, just shimming. I use a foam adhesive to secure ICF to footing and fill any openings that concrete could come through.
