Since its first use in the early 70s fibre reinforcement has been successfully applied in numerous projects all over the world for underground. Fibre Reinforced Concrete (FRC) is one of the most used support methods used in the following  underground applications of concrete: 

Spray concrete lining    Precast Segments Cast in Place final lining Mining

This Engineering Corner will support designers, contractors and clients on the use of FRC, both in tunnelling and mining. It's an interactive knowledge platform dedicated to the use of FRC in tunnelling and mining. 

We are a member of various technical committees like:

The correct determination and use of characteristic values helps to achieve optimum material properties for structural designs incorporating Fiber Reinforced Concrete (FRC). This white paper defines characteristic values for FRC and specifies and compares various methods to determine them. In doing so it aims to support FRC designers and contractors.


This white paper looks at the historical evolution of Fiber Reinforced Concrete (FRC), its advantages in precast tunnel segments, the required performance criteria of FRC for precast tunnel segments, and the technical specifications of a proposed type of steel fiber for this application.
