I was just reading the post on blown render and am puzzled about the permeability of bricks.
How do they stop water soaking through the walls on non-rendered houses, if cracked render causes all these problems on rendered houses?
If the bricks are treated with a waterproofing chemical, why don't they just do that before rendering and avoid all the problems that people face when the render fails?
Thanks for enlightenment!
