1.    Self-drilling anchor bolts

The  Self Drilling Anchor Bolts is a unique anchoring systems 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: -     Particulary suitable 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

 

Applications:

1).Tunnelling:-     Radial bolting-     Forepoling -     Face stabilization-     Portal preparation

2).Ground engineering:-     Slope stabilization-     Micro injection pile-     Temporary support anchor-     Soil nailing
