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 (TechSpan®) 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, cattle and pedestrian underpasses, and cut ‘n’ 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 (TechSpan®) 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. TechSpan® arches also have proven use as ammunition storage bunkers in military applications.
Finite element modelling realises the benefits of soil-structure interactions provides optimum structure geometry and size and thus savings in materials consumption. It is possible to achieve complete water tightness of these segmental structures using state-of-the-art products and installation methods.
