Wire or rebar in patio
 
Is it better to use wire or rebar in a 14 x 32 concrete patio? Live in northern Indiana and water doesn't drain well from yard after raining or the snow melts away.

Wire is fine as long as it is installed right,most times it gets left on the bottom,it needs to stay elevated.

raven's right - even aci doesn't recommend any wire/steel UNLESS there's 2" below & above it,,, think the spec reads ' midpoint vertically in a slab +/- 5% - in a 4" thick slab, that equates to .2" - no one can be that accurate. you're far better off placing the conc & installing the proper joints at the correct time,,, fyi, wire mesh adds strength while the green conc is in tension ONLY,,, after the conc cures, all it does is hold the broken pieces together :whistling2: usually the broken pieces are caused by an incorrect joint pattern/size/depth :eek:

You dont have to use wire if you build a proper base by putting down 3" of crusher run and 1" of fill sand. Tamp thoroughly. Along with proper cut joints, this will increase the life of your concrete.

Crusher run for a base is good I would use 57 gravel on top of that for a break, enabling the pad to move with the seasons
