Resulting from decades of research and development, TechSpan® is a buried precast concrete arch system designed to accommodate high fills, heavy live loads, and alternating loading conditions.
With a small footprint and easy and quick to install, TechSpan® is ideal for mining, industrial, and railway applications, and it is gaining popularity in many different markets.
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.
