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 critical geotechnical reinforcement in challenging projects, improving safety and efficiency for global infrastructure.
SupAnchor launches the SupUTS self-drilling hollow anchor, designed for superior load-bearing in challenging geotechnical conditions with integrated construction and anti-corrosion options.
SupAnchor's self-drilling anchor bolts are deployed in a challenging tunneling project, showcasing innovation in geotechnical engineering and ground stabilization for modern infrastructure.
SupAnchor introduces Sup2000 and Sup5000 grout pumps, offering high delivery rates and pressure for efficient tunneling, mining, and anchor applications worldwide.
