View SpecificationWhat Hollow Anchor Bar Is Actually For
A self-drilling hollow anchor bar drills, grouts and anchors in one operation, which is what makes it viable in collapsing ground where a conventional drill and insert sequence cannot be completed.
The bar is the drill string and the reinforcement at the same time, with grout pumped through the hollow core.
What Goes Wrong When This Is Specified Loosely
- Boreholes collapsing before a conventional bar can be inserted
- Couplings failing under installation torque in hard ground
- Grout return not achieved because bit selection did not match the ground
