Re: GSBN:Stone Veneer over Bales

If you don't want to make faux stone using plaster, which would be the
approach with the most integrity, then I would suggest either a detail
similar to a rainscreen, that would allow some ventilation between the stone
and the plaster wall.  Another alternative would be to set small stones in
the plaster, kind of an exposed aggregate on steroids, allowing for some
plaster between the stones to permit vapor diffusion.  You'd have to be
careful that the construction didn't actually cause more leakage than

I think the number of parallel paths that you and I have traveled at times
is most remarkable.

This is Southern California, that is typically hot and dry - this is the
driest winter on record, I'm told. I believe that our "average" rainfall
about 9 Inches (23 Cm), and the most rain that I can recall receiving was
about 26 Inches (66 Cm); not a lot of rain by some standards, but a lot
than in Jordan.

Sounds like the right approach to attach the plaster to the bales and then
the stone to the wall - what kind of waterproofing would you use?

My concern is the one that we have dealt with for years - trapping the
moisture within the walls and creating a wet environment that could/will
promote fungal growth.

I would appreciate that a lot, Senior Lupo
