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 provides efficient ground stabilization in challenging geology, with high-strength hollow bar anchors and corrosion protection for civil engineering projects.
SupAnchor introduces a corrosion-resistant GFRP solid bolt with high tensile strength, lightweight design, and non-conductive properties for slope stabilization, tunnel support, and mining applications.
A European transport project uses SupAnchor's self drilling anchor system to stabilize loose overburden and fractured rock. Hollow bar anchors provide immediate load capacity, corrosion protection, and long-term geotechnical safety.
SupAnchor introduces SupFRP® GFRP reinforcement rebar with high tensile strength, corrosion resistance, and versatile shapes for demanding construction applications across Europe and North America.
SupAnchor introduces a stainless steel self-drilling hollow anchor combining 3-in-1 drilling, grouting, and reinforcing with superior corrosion resistance for marine, chemical, and permanent geotechnical applications.
