After the closure of the site for the winter and a resumption of the site postponed due to the pandemic, layer 2 is now in progress. The formwork was dismantled and replaced to implement our two mixtures, load-bearing and insulating. This layer will be equipped with numerous probes to measure the evolution of the water content during the drying process, the construction of the following layers, and once the building is occupied. We will also measure the temperature of the walls.
