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

Unstable ground, collapsing boreholes, and fractured rock can slow down conventional support methods and increase risk. Hollow bar systems overcome these challenges with a self-drilling solution that combines drilling and reinforcement in a single step, enabling fast and reliable installation even in difficult conditions. Ideal for reinforcement, face stabilization, and pre-support, they help improve cycle times while ensuring safe and controlled ground 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.

Dynamic bolts

Dynamic bolts deliver high-capacity ground support in demanding underground conditions under static and dynamic loading. Designed to absorb energy and accommodate ground movement, they control deformation and maintain stability in highly stressed and burst-prone environments. Available as dynamic solid and dynamic friction solutions, they enable efficient installation, rapid load uptake, and reliable performance for safe, durable support.

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.
