The problem would be that the cob element would shrink, and the stone facing
wouldn't, causing distortion and eventual failure.

> I was wondering...  If you built a cob wall about 3 feet thick and had the
outside of it with embedded rocks (about grapefruit sized) so that the
outside looked like a stone wall with cob mortar, would that help or hurt
with possible erosions problems?  On one hand it would seem like it would
help because less cob would be exposed, but the rocks may create channels
that concentrate any run off.  Also would that cause problems with
breathability?
