Hey MO,
I want to concrete my pole barn eventually, so this thread was caught my eye. As many threads on here, the primary subject discussed is not the one listed subject of the thread.
Lots of good info here. Course, Junkman has lots of helpful hints but you have to take his ribbing and doubting Thomas tude along with it. ...and everyone reading this wants to see the results of their suggestions NOW.
From my view, just digesting this whole thread, you've come right along and learned a lot from the wisdom offered on here. I fully understand with something this new to you, your bound to have lots of questions as to the details of how to do it. And there is so much info here, it is easy to miss a point er two. I think your on the right track now and you'll get those pesky poles anchored down, then you'll be able to get back to the business at hand.
I had to deal with dirt on my pole barn floor when i first built it. The dust on everything was very annoying. I asked about other alternatives here on TBN a long while back, and someone suggested 'crush and run'. My PB (pole barn) is 28 x 70 and no way could i consider a concrete floor at that time. Crush and run gravel turned out to be a good alternative. Much better than a dirt floor, and when I eventually put the concrete in the 'crush n run' will make a good base.
Best of luck with your project & I hope things start moving along a little better once you get her anchored down.
