I have a crawlspace in the basement that has a dirt floor right
now. I'd like to lay some sheets of 4x8 plywood (or other
material) on it to make a surface suitable for crawling on or
putting things on.

For crawling, a few planks of 1/2" plywood (exterior) would be
useful.
For storage, consider that you'd like ventilation around the stored
items; I'd try some old pallets, with optional 'wood preservative'
painted on (they won't weather, so stain or real paint are a waste).
I'm lazy, I just strap on some knee pads and a hard hat when it's
time to crawl.

Good ideas here. I have to admit that when i first posted, i wasn't
thinking about the termite angle. I like the idea of the concrete
but i have a feeling i'd make a mess of it as i don't know what i'm
doing. However, the paver idea sounds interesting. I priced it and
the pavers cost the same per square foot as 3/4" plywood and they
would last indefinitely. However, that's also something i've never
done. Do i just level the ground and lay the pavers on top letting
gravity keep them in place or is there something else i need to do to
secure them?

Use pressure treated ply and termite concerns go away.

Around here - central Florida - a sheet of PT 1/2" x 4' x 8' is about 25
bucks. That's about $0.78 sq/ft; pavers run from about $2.00 sq/ft up. An
exception is a 12" x 12" x 1 3/4" concrete "stepping stone"' that is $1..31.

My experience with PT ply is that it will cup unless well secured. Pavers are a great idea. Place over a vapor barrier such as 6mil visqueen on leveled grade. You could always spread sand or quarry fines on top of the existing soil to make leveling more easy, but in your application, I really don't see where that is necessary. I would keep an eye on your local craigslist for pavers. Around here they are pretty plentiful...

I'm in NJ. 1' square pavers (or "step stones") are about $1.56 each. Not out of the question. visqueen will add about $100. What does the plastic do? What would be the downside if i just decided to level the ground and put pavers right on top of it? Do you put anything between the pavers in the cracks (i.e. like grout in bathroom tiles)?
