The ancient building techniques called “ Rammed Earth” is one of the oldest construction methods known to man. Evidence traces it as far back on the human timeline as 8000 BC. The rammed earth materials create a strong and environmentally friendly building. Across the world this unbaked earth system has created homes, palaces, and fortresses. “Commonly used especially in China, the technique was applied to both ancient monuments and vernacular architecture, with the Great Wall utilizing the technique”
What is it ? Rammed earth is made of damp soil or earth that is placed in formwork, and then compressed or rammed into a solid, dense wall. The soil mixture can be sand, clay, silt, gravel, loam and sometimes cement into a building recipe that is then compacted into forms. The wall strength will increase as it cures with the compression and the additional factors of moisture content, soil type, and any stabilizer used.
