I am about 150ft to 175ft from railroad tracks. For my foundation should I use 1 1/2 limestone or 1 1/2 rock in the concrete?
Per windstorm req. 3000 psi concrete?
Do you tell the concrete company when you order?
Would I use wire or cable?
And what should be the depth of all the beams?
Thanks,
Robert
Tom: Well that’s fine. Actually 3,500 is what we use in slabs, but 3,000, it depends on how it’s engineered. Wind Storm doesn’t engineer it for you. Your Wind Storm engineer is going to engineer your foundation, so it’s not a hit and miss or this and that. It’s what your engineer is going to stamp his seal on and what the Wind Storm people will take as the approval to go ahead and build.
Charlie: Would do you use wire or cable in the slab?
Tom: I would not use cable. I would not use wire. I’d use rebar, but I think that’s what he’s referring to.
Charlie: Okay. Finally, what depth should he run his beams in?
Tom: I’m not an engineer man. That’s why you have soil reports done. The engineer has to design for it. You asked me about the limestone or the rock, you always use rock as aggregate. The limestone is too brittle and too soft. As far as rebar, I would go with a conventional rebar and concrete slab. I’m not going to design it from that point.
