Excellent thread, with excellent ideas. Will be very useful when I redo both the garage and barn shops this summer. Thanks, guys.
, making certain that the concrete installers PULL THE MESH UP as they are pouring.
This is a common mistake made by most concrete installers. You cant "Pull the mesh up" while standing on it. Sure they hook it up and maybe get a rock under it if lucky, but the mesh remains on the bottom 1" of the concrete because the workers are constantly walking on it when laying the concrete.
Always make the reinforcing contractor lay the rebar or mesh on a concrete block or plastic coated steel chairs designed for the task , otherwise you are pretty much wasting your time putting in reinforcement.
In "the bottom 1" of the concrete", (4" slab) is exactly where the mesh should be!
When a load is parked/placed on the cured concrete, the top of the concrete will be in compression, and the bottom of the concrete will be in tension.
Concrete is wonderful in compression, and horrible in tension..... thus in a floor, any reinforcing should be in the bottom 1/4.
It is possible to keep the wire pulled up, but that only happens with a most conscientious concrete crew.
Supporting the wire with thin concrete bricks or concrete chairs (lots of them) is a good idea.
Put porches over every door. Both walk through doors, and roll up doors. I'm in the process of doing that to my current shop and will include it in my next one.
In my last few shops I run 12/3 romex. With that I have 2 20a circuits at every plug location. I also have a 240v and 120v circuit/outlets near the bay door/doors that lead to the entry. We all end up working on stuff outside.
