Radial bolts

Radial bolts are a key component of primary ground support in tunneling, used in combination with shotcrete and steel sets to ensure excavation stability. Installed in pre-drilled holes or as self-drilling systems, they reinforce the rock mass, improve load-bearing capacity, and form a stable support arch.
By increasing resistance to tensile and shear forces, radial bolts control ground deformation and stabilize varying geological conditions. Proper selection of bolt type and installation method is essential for reliable and efficient tunnel support.

Our bolt solutions

Combination type bolts

Combination type bolts combine immediate mechanical anchorage with the long-term security of a fully grouted system. Its two-step installation enables fast support, flexible grouting, and durable performance with full-length corrosion protection.

Hollow bar systems

Hollow Bar Systems are self-drilling ground support solutions for underground mining and civil engineering. Combining drilling, flushing, grouting, and reinforcement in a single system, they are ideal for bolting, face stabilization, forepoling, micropiles, and ground anchors, especially in weak ground and unstable borehole conditions.

Omega-Bolt®

The Omega-Bolt® is an expandable friction and inflatable rock bolt. The bolt is easy to install with no bonding agent required and is fully activated immediately after installation. Each product in the Omega-Bolt® series is engineered to provide reliable performance, ease of installation and tailored solutions for different geological conditions.

Cable bolts

Cable bolt solutions provide reliable support and reinforcement in large underground excavations. Designed for optimal load transfer and flexibility, they adapt to complex and varying ground conditions.The Fast Cable Anchor, Titan Bolt, and EziTen Cable Bolt ensure high-capacity support, improving stability, safety, and long-term performance in demanding mining and tunneling environments.

Glass-reinforced plastic (GRP) bolts

Glass-reinforced plastic (GRP) bolts offer a lightweight, corrosion-resistant alternative to steel ground support. Combining high tensile strength with easy cuttability, they are ideal for modern tunneling and mechanical excavation. Commonly used as cuttable bolts, injection lances and forepoling elements, GRP systems deliver reliable performance in demanding underground environments.
