Wire Mesh Gauge

[RNeumann]

Thanks, for picking up on the question. that is the mesh type I was referring. It is a #6 (2.9) and that is size that starts to look like mini rebar on 6" squares. And from there you can get some pretty heavy duty mesh panels. I did find a two part engineering firm video and (frost heave region) stating and illustrating why rebar should be place in Top Half of slab.

Redlands Oakie, yes it is science with a lot of variables but opinions even with seasoned installers come in play. Engineers have varying opinions, no difference.

Oldoak....good summary on typical slab and success without over thinking it.

Rneumann...Lol...you are probably right...though it seems recommendations is #3 should be placed 18" spacing.

Thanks all for responses...

Yep 16-18" is the "standard." That's my point- I think even at 24" OC is provides a better long term product than wire. Also remember wire covers less than 28sf because of the overlap.
