Composite Rock Bolts and Rebar for demanding conditions
Technical features applications and performance advantages
Technical features
Composite design engineered for strength and durability
Rock Bolt and Rebar products are formed from continuous fibres embedded in a selected resin matrix. Fibre alignment cross section and surface profile are chosen to achieve high tensile capacity and reliable bond performance.
- High tensile capacity from aligned continuous fibres
- Corrosion resistance in aggressive environments
- Surface profile configured to support bond with grout or concrete
Applications
Usage across mining operations and structural works
Tunnel Support
Stabilising underground excavations
Composite Rock Bolts provide structural stability in tunnel applications by controlling ground movement and supporting surrounding rock during excavation and long-term operation.
Slope Support
Reinforcement for embankments and high walls
Rock Bolts are used to stabilise steep slopes where shear movement or weathering may compromise safety. Composite materials prevent corrosion in exposed environments.
Foundation Support
Load transfer and retaining structures
Rock Bolts and anchoring systems support foundation walls retaining structures and early-stage excavations by improving soil and rock mass stability under applied loads.
Mine Support
Support systems for working faces and haulages
Composite Rock Bolts provide safe reliable support in underground mining operations including tunnels stopes and haulages where high load capacity and corrosion resistance are essential.
Performance advantages
Reasons to choose composite Rock Bolts and Rebar
The combination of high tensile strength low weight and resistance to corrosion creates a strong case for composite reinforcement. These advantages result in improved service life easier handling and a reduction in unplanned maintenance.
High strength to weight ratio
No rust or spalling
Reduced manual handling risk
Non conductive reinforcement
Safety and durability
Supporting safe operations and long design life
Lightweight and non sparking materials assist with safe installation in confined spaces. Long term durability supports reliable performance over the life of the support or structure.
- Improved manual handling
Lower mass per metre helps reduce strain for workers during installation and handling.
- Resistance to harsh exposure
Composite materials resist moisture chemicals and saline environments that cause traditional reinforcement to deteriorate.
- Non conductive behaviour
Non metallic reinforcement assists where stray currents or electromagnetic interference are concerns for plant and equipment.
Installation benefits
Fibre and resin systems that support stable performance
The composition of Rock Bolts and Rebar is engineered to match expected loading and exposure conditions. Fibre content and resin formulation can be adapted for specific project requirements.
- Continuous reinforcement fibres aligned primarily along the axis of the element.
- Resin matrices selected for chemical resistance and stability under load.
- Simplified cutting and trimming using appropriate tools.
