Rammed earth walls are the most traditional structures. Non-valuable earth will turn to the beautiful and long lasting building. High-quality rammed earth walls are as strong and durable as stone masonry walls, in addition they are ecological and environmental-friendly. One can construct these walls either outside or inside the house and build the floors also.

The mixtures for constructing rammed earth walls consist from clay, sand and numerous additives of natural fibers.
