And since it's already too late to change

I find that a strange remark.

Now say it would be completely wrong, so wrong that it needs to be redone. Is it then better to redo the slab before the rest of the house is built or should you do it after a few years when the house is in place?

Sometimes people become a bit blind to the pace and think it's too late to address problems, but the truth is usually that it just becomes more difficult and expensive to fix the problem the longer you wait.
