Tunnelling

Applications include:
Fibre reinforced shotcrete for use in both temporary & final linings; precast tunnel segments for use with TBM's; cast in situ linings; inverts; cable and water ducts; border elements; pavements; kerbs.

High performance, QA guaranteed, Dramix® Steel fibres are commonly used in both dry and wet sprayed concrete to replace the traditional and complicated 1 or 2 layers of mesh reinforcement, thereby providing substantial technical, economical and safety benefit for shotcrete.

They can also be used in cast or precast applications either in combination with, or to completely replace mesh/bar, to provide concrete elements that are not only easier and faster to construct but offer enhanced performance in terms of load carrying capacity, impact resistance, durability and fatigue performance.
