Rock Reinforcement
Our aim is to improve safety, increase productivity, reduce cost, save time and minimize risks in underground mining, tunnelling and construction of underground spaces.
Self-drilling Anchors
A complete range of self-drilling bolts for accelerated installation in any ground condition and the best solution for drilling in unconsolidated and fractured ground.
Self Drilling Anchor (SDA)
- Injectable bolting system that combines support-hole drilling and permanent reinforcement installation
Self-Drilling Dynamic Bolts (SDDB®)
- Hollow, deformable bolt with an R32 ISO thread at both ends and a smooth de-bonded center section
GFRP Self-Drilling Bolts
- Drill and anchor in one step - no pre-drilling needed
- Fast installation in weak or complex ground
- Lightweight, corrosion-resistant, and cuttable
GFRP (Glass Fiber Reinforced Bolts)
Normet offers a wide range of GFRP supports as an alternative to steel systems. GFRP is a composite material made of high-tensile fibers embedded in a polyester or epoxy resin matrix. This composition offers unique properties such as exceptional tensile strength, lightweight, corrosion resistance, cuttability and durability.
GFRP Fully Thread Bolts
- Available in solid and hollow versions
- High tensile strength with long-term durability
- Easy to handle, corrosion-free, and safe to cut
GFRP Self-Drilling Bolts
- Drill and anchor in one step - no pre-drilling needed
- Fast installation in weak or complex ground
- Lightweight, corrosion-resistant, and cuttable
GFRP Combination Bolts
- Hybrid design for mechanical and chemical anchorage
- Lightweight and easy to install
- Ideal for temporary tunnel support with cuttable performance
