Self-drilling hollow anchor system has been used widely as a new technology for slope stabilization.
Self-drilling hollow bar is full threaded, in which system coupler is used to increase the length, and drill bit with different design for different stratum is installed in the front end as drilling forward, with following advantages:
- Highly increased drilling and installation efficiency. Labor cost saved huge.
- Excellent adaption to difficult rock foundation.
SupAnchor R38N self-drilling hollow anchor system was safely installed in False Creek Project in Vancouver, Canada, in 2015.

A recent construction project utilized SupAnchor's self-drilling anchor bolts to stabilize loose soils and rock, showcasing advanced geotechnical reinforcement solutions for demanding civil engineering works.
SupAnchor unveils a corrosion-resistant GFRP solid bolt with up to 500kN tensile strength for slope stabilization, tunneling, and mining. Lightweight, non-conductive, and maintenance-free solution.
Innovative self-drilling anchor system by SupAnchor overcomes difficult geology in a vital infrastructure project, enhancing safety and efficiency.
In a challenging highway expansion project through unstable terrain, engineers deployed SupAnchor's innovative self-drilling anchor system to ensure long-term slope stability and traffic safety.
SupAnchor launches the SupCT Bolt System, a combination bolt with duplex corrosion protection, offered in steel and GFRP variants, delivering high load capacity and up to 150-year service life for demanding tunneling, mining, and slope projects.
