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 bolts provide robust geotechnical reinforcement in challenging construction sites, improving safety and efficiency for European infrastructure projects.
SupAnchor introduces GFRP Mesh, offering superior corrosion resistance, strength, and non-conductivity for applications in concrete repair, highway overlays, and geotechnical reinforcement systems.
How SupAnchor's advanced self drilling anchor bolts enhance safety and efficiency in tunneling and slope stabilization projects across Europe and America, aligning with global infrastructure trends.
SupAnchor's SupUTS self-drilling hollow anchor offers enhanced load-bearing capacity and streamlined construction, ideal for demanding geotechnical reinforcement systems in infrastructure and tunneling projects.
