Precast concrete - Matière
Matière is a patented technology used for building vaulted engineering structures with lengthwise and crosswise fracturing. The Matière technology is especially suited for constructing:
- cut and cover tunnels;
- hydraulic structures;
- outlet works.
Since 1983, more than 8000 engineering structures have been built using the patented Matière technology. Some of them are shown below.
