SupAnchor® Self Drilling Hollow Bars is an unique anchoring system and is today’s answer to the increasing demands of the tunnelling industry and ground engineering for safer and faster production. The system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.

 

Features and Advantages:

Fits SupAnchor® standard Boomer, ROC and Mustang rigs. Particularly suitable for difficult ground conditions.

• A high rate of installation since drilling, placing  and grouting can be performed in one single operation.

• Self drilling system eliminates the requirement for a cased borehole.

• Installation with simultaneous drilling and grouting possible.

• Easy installation in all directions, also upwards.

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

• Simple post grouting system.
