Crusher run under pole barn

[bspeedy]

I'll vote against the crusher run for one reason - dust. When I had it inside my barn, it made a huge dust cloud every time I'd start my truck or tractor. Just seemed like lots of fine stuff to get into air filters and all over everything. Yes - it compacts well. I have a 1/4 mile driveway and it is crusher run and I am happy with it. Perhaps some other product without all the fines for a covered surface. That is what I would use were I to do it again. As for my barn, I finally got concrete in there and I am oh-so-happy with that. But it is cost prohibitive.

Mine stays ever so slightly damp from ground moisture. But my tractor barn floor is "below grade" with an adjacent hill right beside it so it would make sense that it would not be quite as dry as some. I wonder if in your case you could have taken a bit of motor oil in a sprayer and put a coat or two on top of your floor to keep the dust settled?

Have you tried wetting it down a couple times to wash in the fines ? We have a 60 X 60 that we top dressed with 3/8 minus and once it was wet and packed it has been fine, it stays packed tight unless you drag something like a trailer jack or something in it.

You can always mix in some cement with a road base mix to create a 'lean-mix' concrete. Compact that and you'll have the fines locking the slightly larger rocks with the cement keeping it all together in a solid floor. You can dig it out if you really need to or out a concrete slab over it later if you want.

Compaction and moisture content are the keys to getting a good result.
