The CROSS business lines focus on technologies and applications related to crossing structures. Reinforced Earth® true and integral Bridge Abutments (TechAbutment™) are the preferred choice for bridge engineers, EPC contractors and private project developers.

Precast concrete arch (TerraArch™) and box (TechBox™) structures are used for the construction of minor bridges in single or multiple spans, hydraulic passes, material and water conveyance tunnels,vehicle and pedestrian underpasses, and cut and cover tunnels. As an expansion to the technique, these structures are also used as extensions to tunnel portals and construct hydraulically pushed tunnel envelopes. Both precast box (TechBox™) and precast arch (TerraArch™) structures can be used to act as rockfall and debris flow sheds and shelters, as a more reliable alternative for prevention and mitigation of geohazards. TerraArch™ arches also have proven used as ammunition storage bunkers in military applications.

Finite element modelling realises the benefits of soil-structure interactions through optimum structure geometry and size. Thus, this reduces consumption of materials. It is possible to achieve complete water tightness in these segmental structures using state-of-the-art products and installation methods.
