OK - It looks like I'll skip the wire mesh. That will save a few $ which is nice.
Nealtw, you got me rethinking another part of my plan. Moisture should not be a problem in the basement but I am planning on installing a perimeter drain under the slab just to be safe. I was also planning on laying a few inches of gravel under the whole slab as well, followed by a vapor barrier, before I place the concrete.
I know its a good idea to have a perimeter drain, but is it really necessary to have gravel under the entire slab? If not, I'll be real happy to save that expense as well.
