TIL the hard way about rebar placement in cold weather pours

Did a slab pour at a parking lot expansion in Cleveland back in January and half the rebar chairs sank into the frozen mud before we even started. Ended up having to pull rebar up by hand while the concrete was going down, which was a mess. Has anyone else dealt with chairs sinking in frozen ground on a bigger pour?

Heard a contractor say frozen ground just eats those plastic chairs alive.

Plastic chairs and cold weather is a disaster. Left mine out last winter, temp dropped to like negative ten. Came back in spring, found one leg just snapped clean off. Looked like it was chewed by a dog. Total junk now.
