Hi all,

My father in-law came to visit and we started talking about adding to the current slab. I'm very handy and love construction but have never done cement work. I want to know from the more experienced members if this is the right way of doing it and if it will last. I know it's a little late. :no: The rebar is 1/2 inch and about every 18 inches epoxied into the home's foundation and the sides of the existing slab. The thickness is about 5 to 6 inches and it was compacted before the pour. Tell me what ya'll think. :)

I never would have attacted the slab to the house.
A slab will move up and down a house foundation should not.
There should have just been an expantion gap between the house and the slab.
I've never even seen rebar used in a slab extention like that.

Please go back and add your location to your profile.
Simple as going to Quick links and edit.
Even in a garage slab it's only needed on the outside in the footing.

Sorry, trying to get my post count up as well. If I were to decide to finish the other side, should I just do the same thing or not tie it into the house? In the near future, we are going to put a pool in. Is there going to be a problem tying these slabs together? What if I decide to put a cover on the patio?

Great Job. The rebar is probably overkill for a slab on grade, and it should be about 1/3 from the bottom, but the job looks great. I personally like a sponge float finish, but thats personal. Pinning to the foundation is probably fine in FL. Did you tap the forms to get rid of honeycombs and edge it?

Wet it down three times a day for a couple of weeks. :thumbsup:

The rebar in the slab is not a problem just extra expense that is not really needed. The main problem if you are in a frost area is the attachment to the house. The sidewalk will raise and lower with winter frost. I have seen walls lifted an inch when the sidewalk was attached to the wall.

dimensions of the slab ? turn'd down edge ? w/o more scored / diamond-saw'd joints ? jnt pattern ?,,concrete OR ceement ? :thumbsup:

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 ? :eek:

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 :laughing:

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 ) :no:

other'n all the above, nice work,,, next time, try putting it in right-side-up the 1st time :eek:
