As an experienced builder, it’s fun to think of ways to improve productivity. Just imagine all the time and money you’ll save. This blog post explores three realistic earthbag building options: 1x = typical earthbag method; 2x = polypropylene tubes instead of bags; 3x = mechanized hyperadobe (raschel mesh tubes) on curved walls. (Note: An earthbag machine with 4x potential will be tested soon in Nepal, but we’ll save that for a later date.)
