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 was deployed to stabilize a critical slope in a European highway expansion, overcoming loose rock and high groundwater with its unique hollow bar design.
SupAnchor's self drilling anchor system overcomes difficult geology in highway tunnel construction, ensuring ground stabilization and long-term safety.
Breakthrough GFRP hollow injection bolt from SupAnchor delivers high tensile strength, corrosion resistance, and full grouting for long-term tunnel and mine stability.
SupAnchor's self-drilling anchor system utilized in a challenging transportation project, delivering efficient ground stabilization and geotechnical reinforcement in difficult geology.
SupAnchor’s self-drilling anchor system was deployed in a European highway expansion to stabilize steep slopes amid difficult geology, showcasing advanced geotechnical reinforcement.
