Shody,
	Your quote, I'm sure you noticed, said, "some soil environments are  
not suitable...particularly...poor load bearing soils," which would  
include sandy soil because sand shifts. They built the pyramids in  
Egypt on top of solid limestone. There is no telling how much sand  
they actually removed to get to that solid base. For any big project  
like cob, stone or concrete the foundation has to be solid,  
preferably on solid rock. How do others build in that area?
