Terre Armée offers engineered solutions for tunnels and underground structure applications.
Buried concrete arches and box tunnels
For more than 30 years, our teams have designed and furnished precast concrete arch tunnels for different types of sectors and clients. Our TechSpan® and TechBox™ solutions allow for a predictable and economic means for constructing underground tunnels. Our solutions deliver a very competitive alternative for the construction of cut and fill tunnels and underpasses, and are often used efficiently in combination with Terre Armée retaining walls.
