3, no pre-drilling of a borehole by using a casing tube and extension rods with subsequent anchor installationnecessary.
4, minor space requirement for the accomplishment of anchoring.
5, optimized machinery and manpower requirements.
6, basic dimensioning of the required anchoring forces by choosing the appropriate anchor type.
7, optimum bonding of the profiled anchor rod and the grout.
8, adjustment of the drill bit design and diameter to different rock mass and ground conditions.
9, simple anti-corrosion method available.
10, appropriate for temporary or permanent applications
