Inside Austria’s Rammed Earth Factory: No Cement, Just Earth – Revolutionizing Sustainable Building

Let's bring you all down to earth again: Explore sustainable building materials on a groundbreaking scale in this episode of Reconstructing the World! We continue our journey in Austria at Lehm Ton Erde, where Professor Martin Rausch showcases the powerful potential of rammed earth construction. Using only natural materials like clay, gravel, and local stones—without any cement or concrete—Martin's team creates earth-based building elements with minimal CO2 emissions and unmatched thermal mass.

Tour their massive facility and discover the incredible processes involved in creating durable, eco-friendly walls. Learn how this modernized ancient technique, from adaptive formwork molds to the “Roberta” ramming machine, makes rammed earth construction feasible for large-scale projects. Not only do these walls have impressive structural integrity, but they also regulate indoor climates, reduce condensation, and create healthier indoor air quality.

From hybrid timber-and-earth constructions to energy-efficient office buildings, see how rammed earth is transforming sustainable architecture. Could this be the ultimate solution for a greener future in construction?

Watch to find out why rammed earth could become the top choice for sustainable and resilient buildings! To find out more about the amazing work at Lehm Ton Erde, visit https://www.lehmtonerde.at/en/ (Not sponsored!)
