It's used by compacting little by little to make one solid brick
It can be used entirely by itself, making a very strong structure, or be used to coat Earthbag, Hyperadobe, and Strawbale homes
Furthermore, it can be used with art and design in mind. Creating houses you'd otherwise never see
Cob is also very earthquake, hurricane, and tsunami resistant. Very commonly these are the last homes standing
Insulation-wise, these homes use little to no heating or cooling in most any environment and as an additive they are very sound proof giving plenty of privacy
Cob
This is the cheapest option and yet the strongest, but the most labor intensive
Cob is used in all of these options as the final layer and can be used as a design feature
It is also used in the home for many uses like rocket stoves, tubs, furniture, etc
Hyperabobe
This is the second cheapest option for a high-efficiency home, and also the newest option
This is basically standard adobe, but instead of using bricks you're making long continuous brick
This process is much faster then molding, drying, and placing bricks
This is also far stronger than standard Adobe but not quite as strong as cob, though cob is used for the exterior and interior
Earthbag
This is the third cheapest and has been around for long time
Usually built with don't like structures, these are poly bags filled with dirt or gravel with Barbwire and between the hold them from sliding and lastly coated with cob
This is very time-consuming and relatively expensive which is why hyperadobe is slowly taking over
Strawbale
This is the most expensive option, but at least labor-intensive and building is very similar to Standard housing but with much thicker walls
This option requires a lot of lumber and tools but yeah is still far cheaper, more efficient, and easier to build than standard home
These homes are still very efficient and surprisingly have a better fire rating then any standard home
