Material and its Properties
Clay, marl, and material excavated on site are mixed and compacted in a formwork and then layered in blocks to build the walls. Thanks to the plasticity of the loam, the seams can be retouched giving the overall structure a homogeneous appearance. To arrest erosion caused by wind and rain, a trass mortar achieved mixing volcanic tuff (trass) with lime, is compacted every 8 layers of the earth directly in the formwork.
Earth as a material that regulates humidity has a positive, sustainable effect on the use of energy and overall climate control.
