Yes, we placed them in the core. One collar near the inside edge, one near the outside edge. I am real sure about that; it was easy to tell from prior compaction by the vibrating sheepsfoot roller where the boundaries were.

I suspect there are several ways to place anti-seep collars well (just like there are a variety of materials that can be used for collars). This was just one of them.
