No casings required, because anchor bars can be drilled into loose soils without needing casings to support the boreholes.
Fast drilling and installation, because drilling, installation and grouting are in a single operation.
Both rope threads and trapezoid threads are robust and ideal for rotary-percussive drilling and ensuring a high level of bond with the borehole gout.
The hollow core not only serves for flushing during drilling, but also for grouting after drilling.
Continuous threads ensure the bars can be cut and coupled at any point, or extended.
Different anchor bits are available for different ground conditions.
