6. How much water gets under there ?

Yes the insulation will make a difference. Staple is good a way as any. Chicken wire is a lot of work . I've used string in a criss cross
method to hold it up.I've use lathing, I've used steel rods too. The insulation does drop down in places from time to time, but since you have a pump under there you check on that from time to time so you can keep an eye on the insulation too.

Throw down sheet plastic /Biscayne as a vapor barrier ,thats always good thing to do.

All the advice given to you is first rate.

It's always a good idea to get a consult at your hardware store ,home depot wherever, someone that works in lumber,knows about insulation,gutters ,concrete all that. The thickness of yer insulation is determined by the width of yer joists and the width of yer insulation is determined by the spacing between yer joists.16" 18'"so on . And to determine how much insulation you need of course,
you must do the measurements. ! It is not uncommon in older homes for the spacing between joist to vary somewhat although
the spacing should be consistent with the occasional off measure-.usually the off measure is less than the standard-if it's 18 "'s on center there may be a few 14"'s or 16"'s in the mix, end the run ,chimneys and other such.





Good luck with your project.
