55% reduced costs per drilled meter – the new Large PCD Drill Bit Coal provides improved efficiency and increased productivity for coal mining.

The OneStep Bolt is a self-drilling rock bolt that integrates the drill head, drill steel, bolt, and adhesive resin into a single unit. The design streamlines the installation process by combining drilling, resin capsule insertion, and bolt setting into one step. This means faster installation times, improved installation quality, and enhanced safety in underground mining operations.

Drainage and injection drilling systems are essential for stability and safety in tunneling and geotechnical works. Our systems control groundwater, reduce pressure, and prevent erosion and water ingress. They install easily with standard drilling equipment, ensure controlled discharge, and can be enhanced with vacuum pumps for low-permeability ground — delivering reliable dewatering for temporary or permanent applications.

The DSI Hollow Bar System is a versatile, self-drilling solution for ground control in both underground and civil engineering applications. It combines drilling, flushing, grouting, and anchoring in one efficient system, making it ideal for challenging ground conditions.

The AT-GRP Injection System is a self-drilling solution using glass-fiber-reinforced pipes for ground improvement or waterproofing, especially where steel is not desired or where TBMs will later excavate the pipes. It offers flexible installation in both jointed rock and weak ground, with adaptable tube lengths and compatibility with standard drilling equipment and TBM setups.

Friction bolts are a key solution for immediate ground support in mining operations. They stabilize rock masses quickly and efficiently, and can be easily installed with standard drilling equipment. Friction bolts are effective in environments where rapid stabilization is required.

AT – Tubespile™ Vacuum Lances are designed for temporary or semi-temporary drainage around the tunnel perimeter. The system uses an exterior steel tube with a PVC drainage tube inserted after drilling and operates as an uncoupled, single-pass solution. By reducing water content in the surrounding ground, it enhances stability and supports safe excavation.

High-strength friction bolts engineered for reliable ground support and easy load testing.

Friction Bolts are manufactured from high strength steel tube which has a slot along its entire length. A ring, or collar, is welded on the outer end to hold a domed plate to the rock surface.

Hollow core bolts are engineered with a central hollow design, making them perfect for injecting grout or resin during or after installation. This ensures a secure bond with surrounding materials, anchorage strength and load transfer for superior structural integrity. Designed for efficient grouting and easy installation. Hollow core bolts provide load transfer and allow for post-installation grouting, enhancing stability and safety in a variety of conditions.
