Despite the fact you’ll never get it off if you don’t want the there, concrete doesn’t bond to concrete, and that includes block. Those bits that are faked in there with the 8s; not cool. Not ok. They’re likely not even saving money, because they had to pay someone to cut them which would invalidate the few cents saved on the smaller blocks. This is a shit show. And it’s what someone is going to build thier hopes, dreams, and life on. Not ok. At all.
