Frequently Asked Question
What are GFRP Rockbolts?
GFRP Rockbolts are corrosion-resistant ground support bolts for tunnels and underground works.
Why choose GFRP instead of steel rockbolts?
They are corrosion-resistant and can be cut by excavation equipment without tool damage.
How are they installed?
Using standard resin or cementitious grouts with compatible accessories.
Are they suitable for all rock types?
Yes, when designed with appropriate capacity and installation method.
Can they be left in place during re-excavation?
Yes. They can be cut through by TBMs without sparking or severe wear.
