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 successfully overcame difficult ground conditions in a major European infrastructure project, demonstrating advanced geotechnical reinforcement effectiveness.
