Self Drilling Anchors

The use of self-drilling hollow core bar anchors offers the following advantages:

• Fast and highly flexible operation with small drilling rigs.
• Installation without the use of drill casing eliminates drill string removal.
• Installation and grout injection in a single operation.
• Complete flexibility in anchor working loads due to extensive range of available cross-sections.
• Extensive range of different drill bits offering complete flexibility in adapting to prevailing ground conditions.
• Appropriate modifications to the drill mast facilitate drilling multiple self-drilling anchors simultaneously with a single rig.
• The hollow core steel bar facilitates not only flushing during drilling, but also grout injection for anchors and soil nails. It also aids drainage of the soil.
• Can also be deployed as a permanent pile.
