Steel cable anchoring system for deep rock reinforcement and large underground excavations.
Cable Bolts for Deep Reinforcement of Underground Excavations
Cable Bolts are ground support systems designed to provide deep reinforcement of rock masses where longer anchorage lengths are required than those typically achieved with conventional rock bolts.
Manufactured from high-strength steel cable, they can be installed using resin or cement grout to create an anchoring system capable of transferring loads between the rock mass and the support element.
Cable Bolts are particularly well suited to large chambers, large-section excavations, underground mining operations, and areas where deep and reliable rock reinforcement is required.
