The project involves the construction of a multidisciplinary health centre, comprising 11 medical and paramedical practices, a multi-purpose room and 2 flats. The floor area is 750 m². The building consists of an earth structure with no reinforced concrete, despite being located in seismic zone 4, i.e. with a high seismic potential.
Our aim was to go beyond the current state of the art in raw earth construction, which is mainly limited to self-build detached houses.
To do this, we deployed our production line under real site conditions (transition to TRL8) in order to prove its viability and the possible replicability of the process.
This project is a demonstration of the viability of our solution for projects involving the construction of buildings open to the public, a type of building that is highly demanding in terms of regulations.
Of the 672 tonnes excavated, 85% were recycled in 73 % the shell of the building tonnes for the foundations. If the earthwork had been 0.46 m deeper, it would have been possible to produce 100% of the structural materials on site.
Our solution is 50% less expensive than reinforced concrete This difference is due in particular to the absence of steel and the raw materials. But it's also due to the low level of landfill disposal (5%), an item that weighs heavily on the financial balance sheet
For a building and public works company looking to reduce the carbon footprint of construction, Filiater offers an industrial process for producing earth materials directly on building sites or at storage sites to adopt an optimal low-carbon approach in a circular economy model to drastically reduce the various impacts on the Environment. Filiater manufactures local building materials, such as compressed earth blocks and natural site concrete, from excavated earth and recycled spoil from the construction site. This approach enables optimal and sustainable use of local resources and minimises the consumption of water, energy, and natural resources, while reducing the generation of waste. The building materials produced by Filiater also offer intrinsic hygrothermal properties that naturally improve the comfort of buildings and a healthier indoor environment for occupants (summer comfort).
