Ramming earth has been a method of construction for centuries in various parts of the world. Earth is extracted from the ground and compacted in layers inside specially constructed formwork. After compaction, the formwork is released and moved along to a new position in the wall. In this way, the building goes up rapidly, layer by layer, row by row. Little of no non-renewable energy is needed.
