Self-drilling bolting system provides a reliable and effective anchoring solution in hard and fractured rock formations, gravelly, clayey, soft and heterogeneous grounds. Performing drilling, anchoring and injection processes in a single step provides a faster, safer and more economical application opportunity compared to traditional methods.

Working Principle of the System

Self-drilling bolts have a hollow structure and a special drilling drill bit is mounted on the tip. During the drilling process, cement or injection mortar is injected at the same time, ensuring the stabilization of the ground. In this way, the risk of collapse or loss of filling material is eliminated and the system can be applied reliably even in the most difficult grounds.
