dimensions of the slab ? turn'd down edge ? w/o more scored / diamond-saw'd joints ? jnt pattern ?,,concrete OR ceement ?
in genl, any exterior slab is NEVER tied into an adjacent structure's footing OR foundation OR slab because whatever stress attacks 1 would be transmitted to the other since they're join'd at the hip so to speak,,, another reason is what will obama do w/all those fine folk who make & sell expansion jnt ? how will they make a living & what about their children ? shall they now suffer due to your ignorance ?
bet you never even considered how your thoughtless actions affected their lives, did you ? well, did you ? no, of course not - you knew what to do all along - that's why you're in this forum asking for forgiveness, reinforcement, & whatever salvation we can offer.
excuse me - forgot my meds
ok, i'm back,,, aci recommends 2" of concrete above AND below ANY reinforcement be it rebar OR welded-wire mesh,,, depending on the dimensions ( l & w ), a proper jnt pattern should've been all you need'd,,, w/rebar, a proper jnt pattern is more important,,, w/rebar & certain expansion/contraction due to temp changes, NEVER run rebar across a jnt unless its an interior slab ( warehouse floor )
other'n all the above, nice work,,, next time, try putting it in right-side-up the 1st time
if you hear it from a guy in the apron store, be VERY suspicious the mtl/method will work,,, when it time to build something together, they won't answer phones NOR help
