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 highway widening project in mountainous terrain deploys SupAnchor's self drilling anchor system to combat fractured geology, ensuring long-term stability with advanced corrosion protection and high tensile strength.
SupAnchor's SupUTS self-drilling hollow anchor system delivers up to 930 kN tensile strength for deep foundations, tunnels, and slope stabilization. Integrated 3-in-1 design and triple corrosion protection
A recent construction project utilized SupAnchor's self-drilling anchor bolts to stabilize loose soils and rock, showcasing advanced geotechnical reinforcement solutions for demanding civil engineering works.
SupAnchor unveils a corrosion-resistant GFRP solid bolt with up to 500kN tensile strength for slope stabilization, tunneling, and mining. Lightweight, non-conductive, and maintenance-free solution.
Innovative self-drilling anchor system by SupAnchor overcomes difficult geology in a vital infrastructure project, enhancing safety and efficiency.
