Rammed Earth
A wall-building technique compacting local soil in formwork — extremely low in embodied carbon, durable and thermally massive.
Definition
Rammed earth is a construction technique in which moist subsoil — sometimes stabilised with small quantities of cement or lime — is compacted in layers within temporary formwork to create solid monolithic walls. Using abundant local material with minimal processing, it has very low embodied energy and carbon compared with fired brick or concrete, and its thermal mass moderates indoor temperatures.
