[Cob] National Park Service earthbag construction

[Patrick Newberry]

THe white stuff is snow. Cal earth is located in the high desert area of California. Interesting enough, the building with the snow on the right, the covering made from balls of stabilized earth made and placed one at a time. Of course you can get a crew of people making the balls and it can go fast. The reason for this was that Nader figured the cement often cracks due to expansion and contration. Especially in the hot desert. The By using the balls he is sort of predefining where the cracks will be. He then calks the cracks with some type of lime mix I believe.
