CT Bolt

The CT bolt (cuttable combination rock bolt) is a hybrid ground support system that provides both immediate mechanical anchorage and long-term grouted reinforcement. It uses an expansion shell for instant load-bearing capacity and can be fully grouted afterward to ensure continuous load transfer along the entire bolt length.

It is widely used in tunnel excavation support, mining operations, and underground construction where both rapid stabilization and long-term durability are required. Available in various diameters, lengths, and corrosion protection options, it can be adapted for both temporary and permanent applications.
