Drainage plane under fake stone veneer
I’m in a part of the country where rot can be a problem. I want to install some stone veneer, but I am concerned about not having a sufficient drainage plane! Behind the stone/mortar/wire mesh etc., I was thinking of covering the house the way Building Science recommends for stucco–15# felt, a drainage/spacer mat (like Waterway), and 15# felt again. (The tests on synthetic housewraps make me want to stay way far away from it.)
Thing is, I’ve never used or seen a spacer mat. Does it have too much give for a stone veneer application? How do they hold up?
If I’m so worried about water getting trapped, should I just say “forget it” and do a 4″-thick natural stone veneer and have the plans for the footings extended accordingly? Does anyone have ballpark estimates for labor on a natural stone veneer of that sort? I’ve never done that, either.

Greetings R,

Rather than using a drainage mat, we use a rain screen of treated 1"x2" and another layer of ply. We flash the bottom and leave weep holes as with brick veneer.
