Two Piece Arch Systems

TechSpan is our modular three-pin precast concrete arch system that is simple and quick to erect. Suitable for highways, rail, mining and hydraulic applications.

Three-pin TechSpan arches are erected in a staggered and symmetrical manner so that adjacent elements support each other during the erection and backfilling sequence.


This procedure allows a rapid and safe installation, reducing the disruption to the flow of traffic. This is especially beneficial for railway and hydraulic applications.

Where arches are used with Reinforced Earth spandrel walls we can often provide a complete solution for the structure.
