The Self Drilling Anchor system is comprised of a hollow threaded anchor bar with a sacrificial drill bit that performs drilling, anchoring and grouting in a single operation. This system is mainly used in slope stabilization, tunneling pre-support, foundations with micro piles, and is widely applied in mining, railway, and metro construction projects.
Our self-drilling anchor bolts are a bolting solution for unstable ground conditions such as sand, gravel, silt, and clay, and in soft to medium fractured rock formations. For projects facing such ground conditions, self-drilling anchors should be considered as the main productivity solution.
