Mechanical Rock Bolt

The mechanical rock bolt is a ground support system that provides immediate anchorage through a mechanical expansion unit at the end of the bolt. It stabilizes the surrounding rock by generating radial pressure within the borehole, ensuring quick and reliable load transfer without the need for immediate grouting.

It is widely used in tunnel excavation support, mining operations, and temporary ground stabilization applications where fast installation is required. Available in different diameters and lengths, it can be used as a standalone support system or in combination with grouting for long-term performance.
