Drainage mat behind stone veneer?

Debra Cedeno| Posted inGreen Building Techniqueson

Question:

Is it preferred to have a drainage mat in the air space with a stone veneer (as I typically specify – EnkaDrain-standard) )

OR

Is it OK/ better to delete the mat and the air space (to minimize the opportunity to form condensation) and fill behind the veneer solid with mortar?

I would provide weeps at the bottom of the wall for water to escape in any case.

Thoughts?

    Debra,
    你想要排水垫和air space -- for sure. Adhered stone veneer installations are VERY problematic, especially over OSB.
