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 self drilling anchor system provided slope stabilization and retaining wall support on a 14.5-km highway expansion in fractured rock, delivering fast installation and high load capacity.
SupAnchor launches the SupShell Expansion Rock Bolt System, a self-drilling anchor system that offers immediate anchorage and efficient grouting for tunnels, mines, and slopes.
SupAnchor's self drilling anchor system and hollow bar anchors provide effective geotechnical reinforcement in a demanding construction project, showcasing innovation and reliability.
SupAnchor introduces SupFRP GFRP rebar with 1000 MPa tensile strength and superior corrosion resistance for marine, underground, and infrastructure projects.
SupAnchor's self drilling anchor system deployed on an Alpine slope stabilization project, showcasing efficient installation and high-performance geotechnical reinforcement in challenging conditions.
