Even if it is pourous it is going to tend to slow what ever moisture is attempting to escape down.

It is not porous in my book. Maybe porous like goretex. Not like a regular foam pad that I can get some air through. Doesn’t accept liquid water, surface is a sheet of rubber but air bubbles inside.
The moisture flow is exactly the reason I’m asking. It’s been successful for 55 years so change might create a problem.
The other consideration, house is heated, crawl space is cold. Moisture has no reason to condense on warm underside of floor. Water Will want to condense on top surface of floor since floor is cold. Maybe no issue?
Gregpark: I gave a link to the product. There’s other pads that look like waffles and which are porous. This stuff is quite stiff and heavy but great to stand on. No embossed pattern, it’s sheet rubber on top and bottom. It doesn’t collapse under weight like all the other stuff I’ve seen, has a more linear spring. It is apparently made to go over concrete radiant floors. Is this still effectively waffle pad? They said no extra charge compared to the foam they usually use (we have that foam upstairs in kids rooms and it sucks.) What would you recommend? The people at the carpet store know nothing - are carpet slangerz. Around here competence is rare and expensive.
I don’t think there are any vents today, except the tunnel to the warm furnace room.
I found some websites that advocate crawlspace ‘encapsulation’, I don’t see harm in taping the current seams. Visquene above… man that will suck to do. Is there a special staple that won’t tear through the sheet?
