I'm still waiting for concrete to be delivered for my footers so i have 2 days to decide this.
I have always understood that rebar is an important structural support in concrete. But I was looking at the DOT index for the culver end wall footers and there is no concrete mentioned in the index. I asked the inspector and he noticed the same thing and was surprised but had no idea why.
My buddy who is a contractor said I should put some rebar in any way and that made sense to me. But another person has since said the dept. of transportation may not want rebar because the footer is always going to be surrounded by water and the rebar would rust swell and crack the concrete.
Does anyone here have knowledge of this. the footer is 24" wide and 16" deep with 4000 psi mix.
If I'm understanding this project correctly, it's in the DOT right of way; if it is, do as they say or you may be sorry. I'm sure they have their reasons for the way it's engineered. It's kind of like sidewalks; they would sure last a lot longer if you could put some rebar in there, but most cities will frown on it in a big way.
Epoxy coated rebar is common for projects like this, but it's not something you'll get at your local hardware store (and it's not cheap).
Makes no sense to me for no rebar. Note, it doesn't swell. I think I would check it in more detail and find out if they just forgot to put anything about rebar in the Index.
Maybe they want fiber in the concrete, what our city has went to for streets and sidewalks instead of rebar. :dunno:
Although I am not familiar with Florida construction specs I am familiar with dealing with city, county, and state inspectors here in Cali. In a nutshell, do it the way THEY want. I have seen too much concrete and pipeline removed because someone thought they knew better than the inspector, did it their way, tore it out and re-did it the inspectors way.
yes it is in the DOT right of way. I think maybe I should do it they way the state tells me too because they may have decided the footer was better without it because of the rusting issue.
But the dot wants rebar dowels placed vertical sticking out of the footer so they will be encased by the wall and at the construction joint there will definitely be water AND air so those dowels will rust even sooner.
If the DOT ever has to remove those footers, they don't want to have to spend the time with a torch cutting rebar to remove the pieces. Not to mention the risk of injury when the bar is cut and the pile shifts.
I was going to use the fiber mix but cemex told me there was absolutely no benefit to it in a footer. They said its only benefit was ti thin slabs 6" and under in thckness for surface cracks.
I was so torn on this. I put rebar in but not much. I kept wondering about the rebar rusting and splitting the concrete because the footer was basically under water.
so one of them got 2 lengths of very thin rebar. I think it was 3/8". t was left over from a recent pool build a friend did.
After I set it up and tied it in place I thought. a lot of good that thin stuff will do on such a large footer so the second one got 2 - 10' lengths of 5/8" rebar. I Was going to swap out the thin stuff on the first one after that but the concrete showed up.
what is done is done. no going back now. I was actually a little short on concrete. I needed like 2.2 yards and I only ordered 2 so I rushed to the HD and picked up 6 80# bags of 5000psi quick crete.
There was plenty of water in the form so I just dumped it in and mixed it in the form.
I'd post a picture but its all covered by an inch of water again so you wouldn't se much more than a mess
