There are several different methods to build using earth.
All of them work. All of them have pros and cons. It just happens that for me, Superadobe has proven to be awesome to work with.
The best thing as that it also can be combined with any other earth building method to satisfy your needs.
There are many good books and articles, blogs and websites in English to learn about Earthbag Building.
