TUNNELING
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.
DRAMIX® can be used in:
- Fibre reinforced shotcrete for use in both temporary & final linings
- Precast tunnel segments for use with TBMs
- Cast in situ linings Track Slabs
- Inverts Cable and Water Ducts
- Border Elements Pavements
- Kerbs
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.

MINING – ABOVE GROUND STRUCTURES

DRAMIX® Steel fibres have been utilised in the mining sector for numerous major projects.
Some of the areas DRAMIX® has been used are:
- Heavy Machinery Workshops Jacking Slabs
- Hard Stands Refuelling Bays
- Wash Down Slabs Tunnel Pavements
- Crusher Foundations Access Roads
DRAMIX® Steel fibres in slabs can either work with conventional mesh/bar to give tighter crack control and enhanced durability or they can completely replace mesh/bar to provide slabs that are not only easier and faster to construct but offer enhanced performance in terms of load carrying capacity, impact resistance and fatigue performance.
MINING & TUNNELLING GROUND SUPPORT
For underground structures both DRAMIX® steel and SYNMIX Synthetics are utilised for:
- Shotcrete Shaft-lining
- Synmix macro fibres are typically used in ground support and other applications where significant deflections, rotations, crack widths and ongoing creep are not of concern
