box tunnels.

NOROQ's box tunnels are particularly suitable for small paths and pedestrian tunnels, fauna passages for watercourse relocations and supply channels.


The advantage of the box tunnel is its water resistance.

The tunnels made of box tunnel elements are watertight directly after installation.


NOROQ's box tunnels are available in various sizes, depending on the static and geometrical

requirements for the structure.

arch tunnels.

NOROQ's arch tunnel represents an aesthetical and economic solution for a wide variety of structures such as underpasses of roads or highways for bicycle and pedestrian crossings as well as underpasses of streams or railways serving as animal crossings.


The arch tunnel is available in standard lengths, whereas other lengths can be produced as well on request.

square tunnels.

To build greater underpasses and bridge structures than those that can be made with box tunnels, NOROQ offers square tunnel systems of various sizes.


The square tunnel consists of top and bottom elements and are used for roads, streams and bigger underpasses. These tunnels can be offered in standard section lengths as well as they can be tailor-made for each project.

steel tunnels.

NOROQ's steel tunnel is a fast and economic solution both in terms of the design and the execution. By adjusting the cross section and due to a wide variety of radiuses and opening angles, it is possible to produce many different steel profiles for a broad scope.

Steel tunnels can be produced for fauna passages and relocations of water courses, path underpasses, pipes and cable trenches etc.

L- and T-elements.

With NOROQ's L- and T-elements achieves great opportunities for storage of all kinds of material. Our L- and T-elements are available in different heights and with different lengths, just after the required needs, as well as with horizontal base plates. Both L-elements and T-elements may be used as one- and two-sided loadable elements.

Both element types are characterized by having vertical sides and that each can stand alone, or that the elements can be used for slope protection.

The required stability of both L- and T-elements is achieved through their own weight and a mutually assembling of flat iron on the back side.

NOROQ’s T-elements has the additional advantage that they do not require a special foundation to ensure their steadiness.
