Opinion on wall bonding and mortar application

Hello,

What is your opinion on the wall connection from interior to exterior walls.

The stone is a KLB (175 mm with 3 chambers) laid with thin-bed mortar.

The construction company talks about butt jointing with glued-in meshes (no idea what kind of meshes these are). This seems to be standard here. The architect says the meshes are rubbish. He wants interlocking. Of course, that is time-consuming, and can it be done with thin-bed mortar? What about flat steel anchors in sufficient (or excessive) quantity?

What do you think about that?

Then about the mortar application.

Actually, this is done with a mortar board. Is there anything against dipping/placing the stone into the mortar and then building it up?

Thanks for your comments

So with us, the walls were also simply built - I believe that is even common nowadays. With us, the walls were connected with wall ties.

Interlocking is certainly the most practical, but it is very disruptive to construction progress. For reasons of time, usually the exterior walls are built first and then the interior walls. I cannot say anything about the nets. With thin-bed mortar, the flat anchors have proven themselves. But be careful to use masonry flat anchors that are actually approved by the construction supervision and not some cut-to-length packaging straps from the brick packages.

Has been taken care of.

Will be interlocked and mortar sled will be used.

Thank you
