Here’s a very interesting perspective of water transport through macro pores of gypsum sheathing.

I’ve scored the facer to allow water and fluorescent dye to migrate beyond the facer during a 5-hour ponding test. After sectioning, I happened up this view of a large macro pore filled with water/dye solution. 

This serves as a great example of how porous materials are rarely homogeneous. And they seldom perform that way.
