I have a concrete retaining wall that would look much better with a natural stone veneer. I live in the western Cascades of the Pacific Northwest where we get a lot of rain and freezing in the winter. I have been gathering a lot of stone, mostly basalt, which varies from 1- to 5-inches thick, and size, some of which are several square feet and as much as 120 pounds. My two main questions are:
What type of morter would be best; and is there a fastening device or anchoring device I can use to keep the larger pieces from falling out?

I was involved in a commercial building many years ago that had granite cladding. They drilled a hole vertically in the stone and glued in a 6 ga solid copper wire, and fastened the other end to the framing. After the joints were caulked, the wire was not visible.
*further to Eds advice...there are stainless ties that do the same job...epoxy or car bog into place..also you can use sheet lead to act as spacers as you go and then grout up the face after..( mortar backs of stone into place)
*b WBA At Your ServiceRick, When you say you have a wall that would look better with a stone veneer, was this wall poured with a 4" - 6" stone shelf for the veneer ? As far as the ties go, you should really stick with a stainless product for an exterior application such as this. It could be as simple as a typical corrugated wall tie that is anchored to the wall mechanically or even with an epoxy product. Your local quality masonry supplier can get these ties for you. Generally, stainless is a special order. If you want a more elaborate tie, you can look in the link below.http://www.anconccl.com/wall_tiesBP.html
