For decades, fully grouted rock bolts have served as the backbone of underground and slope support in mining, tunneling, and civil engineering.The fully grouted solution is engineered for consistent, long-term reinforcement across challenging geological conditions.
1.Core Technical Advantages
◎ Full-Length Grouted Steel bar：
Yidao fully threaded bar is fully encapsulated by cement or resin grout for full-surface bonding, evenly distributing bearing stress to achieve an excellent force / borehole ratio. Fabricated from high-tensile steel, they deliver strong anchorage in smaller boreholes to cut drilling costs, while angle-compensation structures suit complex inclined bore trajectories. Field tests confirm consistent bond strength and stable load capacity when installed with standard grouting procedures.
◎ Customizable Galvanized or Epoxy coated Anti-Corrosion Version
All full grouted anchor series provide galvanized and epoxy coated surface treatment options. The coating isolates steel from humid, saline and corrosive underground environments, effectively avoiding rust damage and extending the service life of long-term permanent support structures.
2. Full-Scenario Application Fields
Yidao fully grouted rock bolts are compatible with both pure rock and mixed rock-soil strata, covering four core engineering scenarios:
◎ Ground support for tunnels & underground mining roadways
◎ Rock stabilization for mountain slopes & landslide control
◎ Deep permanent anchorages in solid hard rock
◎ Composite reinforcement of mixed rock and soil layers
Combining full-length grouting structure, high load efficiency, anti-corrosion customization and cross-strata adaptability, Yidao fully grouted threadbar rock bolts are the cost-effective, reliable anchoring choice for all long-duration geotechnical stabilization projects.
