OVERVIEW: Self Drilling Anchor Bolt Systems
SIGRICARE Self Drilling Anchor Bolt Systems are engineered for demanding geotechnical applications where borehole collapse is prevalent. By combining drilling, hollow bar placement, and pressure grouting into a single continuous pass, our SDA systems maximize installation efficiency, ground bonding, and structural safety across tunnel portals, mining shafts, slope stabilization, and foundation micro-piles.
