The T103 Self-Drilling Anchor System is a versatile solution for a wide range of geotechnical and construction projects. It is specifically designed to provide stability in challenging ground conditions where conventional drilling methods are inefficient or impractical. By combining drilling, grouting, and anchoring into a single process, the system significantly increases project efficiency and reduces overall costs. The T103 system is particularly well-suited for applications that require reliable ground support, even in unstable soil, fractured rock, or loose formations.
Its hollow bar design allows for the simultaneous injection of grout, which stabilizes the borehole and enhances the anchor’s load-bearing capacity.
