Rammed Earth

Rammed earth is an ancient building method that has seen a revival in recent years. It produces noncombustible, thermally massive, strong, and durable buildings. However, walls can be labour-intensive to construct without machinery (powered tampers). Structures are susceptible to water damage if inadequately protected or maintained.
Building a rammed-earth wall involves compressing a damp mixture of earth that has suitable proportions of sand, gravel and clay (sometimes with an added stabilizer) into an externally supported frame or mould. The construction of an entire wall begins with a temporary frame (formwork).
