  • R51 Self Drilling Bolt
Product Details

R51 self drilling bolt is unique anchoring system and fulfills current and increasing demands of the tunneling industry and ground engineering for safer and faster production. This 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

1. Particularly suitable for difficult ground conditions.
2. A high rate of installation since drilling, placing and grouting can be performed in one single operation.
3. Self drilling system eliminates the requirement for a cased borehole.
4. Installation with simultaneous drilling and grouting possible.

 

Application

• Radial bolting
• Slope stabilization
• Fore poling
• Micro injection pile
• Face stabilization
