The images below show Mike Gross of Terra Block Inc., builders of earth block presses and adobe machinery. Mr. Gross bought these Cinva Ram plans and built the manual machine you see here. Step 1- Dirt is loaded into the soil box. 2- The lid is closed, and the long handle is pulled down once. 3- The lid is removed and the pressed brick is raised up for easy removal. The blocks can be used immediately, or stored for later construction. There is no cement or straw in these bricks, only a small amount of water may be added for correct moisture. Information* on preparing soils, testing soils, and making the bricks is on the CD guide via the many books and reports provided.
