Steel Fiber concrete innovations for all tunnel lining structures
What we do

Unique Fibers: Tailored for Every Tunnel Lining!

The underground offers the space which mostly is not available anymore on the surface. Urban traffic is saturated, and rapid mass transport is only possible with a good underground metro network. Service utilities require a dense network of pipes bringing fresh water into the cities and a dense network of sewers to evacuate the wastewater to the water treatment stations. Communication, being the main characteristic of our present world community, needs an extensive network of cables and service stations. The required space is only available underground. Development of modern tunnelling techniques, construction materials and skilled mining people have highly influenced the attractiveness of the underground construction technology. Exploring diverse applications in underground: navigating the parameters for selecting the perfect fiber match.
