TechSpan Precast Arches

The perfect custom-designed arch

Nearly 25 years ago, Terre Armée developed the TechSpan® precast concrete arch system.

This technology is based on the Group's soil expertise and a finite element analysis, which paved the way for the development of this three-hinged system of two funicular curve-shaped parts.
