Hi
Im looking for opinions on the collar pour. Father in Law claims he can pour both the collar and the sidewalk as one piece, and place the stones later. He says he is afraid to get concrete on the stones if they are placed first. I told him that sounds like a bad idea and risky if the forms are off. He demanded an answer why i think that, and the only answer i had was that i havent seen anyone else try it that way. I also think it would require more concrete and thus and increased expense, as i cant imagine a stepped slab like that being strong enough at the union of the collar and the sidewalk without thensidewalk being poured deeper.
Am i off base? He worked in concrete for many years and i did not.
