Wikipedia Definition of Rammed Earth
Â Ramming earth to create walls is at least as old as the Great Wall of China. It is really quite similar to adobe and cob techniques, in that the soil is mostly clay and sand. The difference is that the material is compressed or tamped into place, usually with forms that create very flat vertical surfaces. Modern rammed earth typically utilizes heavy mechanized equipment to move and compress the material . The walls are normally at least a foot thick to give enough bulk to be stable and provide the thermal mass for comfort. It is best to apply insulating material to the outside of the building to keep the interior temperature constant. The interior surface can be finished in a variety of ways, from natural oil to more standard surfaces. Rammed earth houses tend to have a very solid, quiet feeling inside.
