Features and Advantages

1.Particularly suitable for difficult ground conditions.

2.An efficient installation since drilling, placing and grouting can be performed in a single operation, saving both time and money.

3.Self-drilling system eliminates the requirement for a cased borehole in collapsing soils.

4.Fast, single-step anchoring system with simple equipment able to work with standard track drill (top hammer) or hand-held drilling equipment, eliminating the need for larger casing rigs.

5.Installation with simultaneous drilling and grouting possible, and post grouting system is simple.

6.Continuously drilling and grouting under high pressure causes the grout to permeate into looser soils and creates a bulb-effect for increased bond capacity.

7.Easy installation in all directions, also upwards, and similar installation methods for all ground conditions.

8.Suitable for working in limited space, height and in areas of difficult access.

9.Galvanizing for enhanced corrosion protection is available if necessary.

10.Multiple ranges of drill bits suitable for different ground conditions.

11.Continuously threaded bar pattern can be cut and coupled anywhere along its length to achieve all lengths.
