The stratum of Macedonia KO Highway was very complicated with extremely loose and collapsed rock foundation. Solid steel bar can’t support post-reinforcement construction.
Under such circumstances, China Hydropower Engineering Bureau was decided to use SupAnchor Self Drilling Hollow Anchor System which is combined by drilling, grouting and anchoring in one. By using SupAnchor system, the difficult stratus was overcome.

SupAnchor's innovative self-drilling anchor system addresses complex geotechnical challenges in infrastructure projects, ensuring stability and safety in tunneling and slope stabilization.
SupAnchor's R thread self-drilling hollow anchor enhances tunneling and ground projects with its 3-in-1 design, offering faster installation and robust corrosion resistance for global infrastructure.
SupAnchor's self drilling anchor bolts provide robust geotechnical reinforcement in challenging construction sites, improving safety and efficiency for European infrastructure projects.
SupAnchor introduces GFRP Mesh, offering superior corrosion resistance, strength, and non-conductivity for applications in concrete repair, highway overlays, and geotechnical reinforcement systems.
How SupAnchor's advanced self drilling anchor bolts enhance safety and efficiency in tunneling and slope stabilization projects across Europe and America, aligning with global infrastructure trends.
