Lehm Ton Erde rammed earth walls are produced from 100 percent earth with no added cement or chemical binders, making the material free of harmful substances and fully recyclable. The company typically uses excavated or regionally sourced soil in production, reinforcing local material cycles.
These walls can be realised either on-site through shuttering and compaction or as prefabricated elements manufactured under controlled conditions for precision and construction efficiency. Designed to function as both load-bearing structural elements and self-supporting cladding, the natural layering created during compaction becomes a visible record of fabrication.
Rammed earth walls from Lehm Ton Erde are characterised by high thermal mass, enabling them to store and release heat passively and contribute to a balanced indoor climate, and by positive acoustic properties. Natural erosion of exterior surfaces is anticipated and integrated into design, forming part of the material’s life cycle rather than presenting a structural disadvantage.
The manufacturing process and material composition enable infinite recyclability and straightforward maintenance: because the material is water-soluble and monolithic, connections and joints can be repaired repeatedly with the same base earth. This recycling potential supports disassembly and reuse without introducing new pollutants.
