About steel fiber reinforced concrete

Achieving safe, durable and low-carbon lining

Achieving safe, durable and low-carbon lining

Anyone involved in underground construction knows how many factors come into play when designing structures below ground; not to mention the many risks during its construction. Having many decades of experience in the most challenging lining projects in tunnels and mines, we not only have the in-depth expertise and know-how to ensure the safety of these projects, we also offer fiber concrete reinforcement solutions which guarantee a more durable and sustainable underground structure.

We have a wide portfolio of fiber concrete reinforcement solutions, and offer a high quality fiber for each kind of application, whether your project needs primary/ final sprayed concrete linings, cast-in-place or precast segmental linings or temporary/permanently sprayed concrete. Used in numerous tunnels and mines around the world, Dramix® steel fibers have proven themselves as a key component in achieving safe, durable and low- carbon lining.


About steel fiber concrete reinforcement

About steel fiber concrete reinforcement

Steel fiber reinforced concrete (SFRC), as its name suggests, is concrete that has been reinforced with steel fibers. Steel fibers bridge the crack at very small crack openings, transfer stresses and develop post crack strength in the concrete. Unlike conventional reinforcement, which consists of steel bars or mesh, steel fibers are relatively short, discontinuous elements that are randomly distributed throughout the concrete member.

Further, traditional reinforcement is provided at distinct locations, whereas steel fibers form a homogeneous reinforcing network across the entire concrete cross-section, thus providing increased strength.


Sustainable & lowers footprint

Sustainable & lowers footprint

Steel fiber reinforced concrete provides long-term, structural stability in underground projects; the reinforcement support is designed with the future in mind. For example, Dramix® steel fibers enable a service lifespan of concrete tunnels of 120 years, thanks to optimal crack control and structural stability. SFRC lowers your footprint significantly in comparison to traditional reinforcement in two ways: significant steel and concrete savings.
