Excellent discussion on drystone, traditional stone and modern veneer!
I agree completely, although as I think about it, the stone doesn't move.
The mortar moves. Gravity works at both the stone and the mortar equally;
yet the mortar whether it be lime putty or portland cement is usually the
weakest link (although some sandstones and limestones are weaker than portland
mortars). The linseed oil used as waterproofing makes sense. I wonder what the
mix is? The space between mortar and stone is the weakest link.
I will note that stone veneers that follow structural stone practices &
traditions rarely when failing let a crack in a mortar joint run vertically
greater than 12". I have seen numerous examples of 'veneer' walls built soundly
following structural stone principles. Viva la mason. The best walls follow
stuctural principles. They look the best and "feel" the best. The eye knows.
A.E. the Irish Poet first coined the phrase "The Cold Immobile Herd'.
Honor the Herd.
