Underground rock support method


Features and Advantages

• Particulary 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.

• Hot-dipped galvanizing for corrosion protection
