Masonry block holes

I live in South Carolina. I had an inspection on a single family home that had holes in the masonry block (filled with concrete). The holes were only on 2 sides of the structure. Im at loss as to what they holes are for…Could you assist.

Is there an accessible crawlspace?

Possible termite treatment but the holes should have been sealed afterward. I had to treat a house this way once back in the late 80’s

Agreed, looks like termite treatment drill holes.


Look like a slab to me.

Post tension.
