foundation for CMU wall
(OP)
Up north, i have never seen a foundation for CMU wall showing CMU below grade. Is there a problem if we start to lay the CMU from top of the pad below grade? thanks
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

If it a basement wall or a retaining wall, make sure that it is reinforced for the lateral soil loads.

The best way to test something is to squeeze it, slowly, until it breaks!

If it is a basement, you design it with block on the strip footing and the interior slab poured on the footings with 3.5" of concrete in contact with the wall. Reinforcement in the wall may not be required according to the IRC which is based on the IBC emprical design method (Chapter 5).
If it is a frost wall with masonry above, waterproofing may not be required, but the reinforcement pattern must continue. Grouting is of no benefit to "waterproof" a frost wall. Basement waterproofing is first accomplished by water control, then by coatings.
Anyone that makes a blanket statement that masonry is "porous" should think a little more. the absorption of concrete masonry units canbe rediculously low to the point where they are difficult to lay.
You do not "paint" waterproofing.
If you are concerned about the "flash" (flashing?) look at your engineers plans or one of the genally accepted details published by various associations and material suppliers.
