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.

A major highway expansion overcomes unstable geology using SupAnchor's self drilling anchor bolts, featuring hollow bar anchor technology and a drill-and-grout bolt for efficient slope stabilization.
SupAnchor introduces the SupFRP® GFRP Tie Rod, a corrosion-resistant, high-strength alternative to steel tie rods for formwork. With permanent application and easy handling, it reduces costs and enhances project efficiency.
A major infrastructure project overcame difficult geological conditions using SupAnchor's self drilling anchor system. The hollow bar anchors provided reliable ground reinforcement, ensuring long-term stability and safety.
SupAnchor's SupUTS self-drilling hollow anchor offers ultimate loads up to 930 kN, integrating drilling, grouting, and reinforcement for high-load geotechnical projects.
