TechBox™ is a state-of-the-art precast ‘box’ structure, typically a one- or three-segment system suitable for cut ‘n’ cover buried structures. The design is done using the finite element modelling method to optimize section sizes. The precast segments are brought to the installation site, when the site is ready for construction. It allows rapid on-site regulated installation. The soil cover required in TechBox™ structures is lower than for arch structures.
