Aktor has extensive experience and expertise in the field of tunneling engineering works. The company is currently carrying out more than 15 tunneling projects totaling 25km in length throughout Greece. These include hydraulic, railway, road and underground subway tunnels, as well as the configuration of subterranean spaces. Aktor deploys the latest excavation and retaining methods and machinery. Aktor owns a significant amount of specialized machinery: JUMBO drilling machines, anchor drilling and placement machinery, shotcrete machines, tunnel loaders, dumpers and others.
