Terre de Paris, de la matière au matériau

Exhibition book

Published in October 2016
Book only in French

Each year, over twenty million tons of soil are removed in the greater Paris area, to which can be added some forty million tons that will be excavated through 2030 to make room for an upcoming network of subway trains.

Generally left out in the open, it is an issue of great concern. “Terres de Paris” analyzes the soil excavation process, reports on the state of knowledge of our subsoil and reveals a heretofore unexplored potential to imagine a new, more virtuous cycle, no longer ranging from soil to demolition debris, but instead from matter to materials.
When the constraints of soil waste encounter the challenges of construction, innovative concepts take shape. The never-ending development of knowledge and techniques by earth builders, in addition to the knowledge amassed on the composition of Parisian area subsoil, stemming in particular from the 5000 sections bored to accommodate the transportation infrastructures, provide the opportunity to envision another future for excavated soil. Architects Paul-Emmanuel Loiret and Serge Joly carried out this experiment, from the extraction to the workability tests, in conjunction with amàco, a center of excellence on material sciences for sustainable construction, and CRAterre, a global reference in the area of earth architecture.
