Self-Drilling Anchors (SDA) are an injectable bolting system that combines support-hole drilling and permanent reinforcement installation into a single product. SDAs are suited to both single and coupled length configurations and offer rapid installation rates into varied and complex ground conditions, mitigating the need to install temporary support.
