Different Earthen Walls

need different materials, climate, equipment and skills- coming soon

Structural Block Walls 

Adobe, CEB (compressed earth block), ICEB (interlocking CEB):
Brittle unless interlocking and often built on reinforced concrete (RC) footings. 

Structural Stone Walls

Through-stones or reinforcement important. Usually built on RC footings.

Structural Monolithic Walls

Rammed earth, Cob, Puddled adobe:
Brittle except cob, usually reinforced and built on RC footings.

Basics to Build with Earth

Ask local officials what building code applies. Earth building codes for adobe and other techniques exist in some states and are under development for the IBC in general. Code for New Zealand includes structural information.
