Anchoring Systems

Self-Drilling Anchors (SDA)

Drill, grout and anchor in one continuous operation.

Self-drilling anchors combine drilling, grouting and reinforcement in one continuous operation. The hollow threaded bar acts as both drill rod and permanent anchor, making the system ideal for unstable ground where conventional boreholes may collapse.

• Drill, install and grout in one operation
• No casing or pre-drilling required
• Fast and cost-effective installation
• Suitable for collapsing ground
• Continuous grout improves bond
• Easy extension with couplers
• Reduced equipment and labour
• Suitable for restricted access
