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.
Dynamic Bolts
Rock bolts with unique anchoring system that enables superior energy absorption especially in dynamic conditions.
D-Bolt®
- Dynamic rock bolt
Self-Drilling Dynamic Bolts (SDDB®)
- Hollow, deformable bolt with an R32 ISO thread at both ends and a smooth de-bonded center section
HD-Bolt
- Hollow dynamic bolt
HX-Bolt - Hollow hybrid dynamic bolt
- Hybrid anchorage system
Dynamic Yielding Cables
- Innovative cable bolt solution engineered for dynamic ground conditions
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
