Tunnel Construction

Road tunnels, railway tunnels and hydro tunnels executed by Kuberagroup using TBM, NATM and drill-and-blast methodologies.

Home / Services / Tunnel Construction

Kuberagroup delivers tunnel construction services for road, railway and hydroelectric projects — including adits, main tunnels, access tunnels and cut-and-cover tunnel sections using modern tunnelling methodologies.

Tunnelling Capabilities

  • Road Tunnels — twin-tube and single-tube tunnels with NATM support systems
  • Railway Tunnels — alignment-precise tunnels for metro and rail corridors
  • Hydro Tunnels — pressure tunnels, penstock tunnels and water conductor systems
  • Cut-and-Cover Tunnels — urban tunnel sections with top-down or bottom-up methods

Methodologies We Use

Depending on geology and project requirements, we deploy TBM (Tunnel Boring Machine), NATM (New Austrian Tunnelling Method), drill-and-blast and cut-and-cover. Our workflow covers exploratory drilling, probing, blasting or mechanised excavation, primary support (shotcrete, rock bolts, steel ribs), waterproofing, secondary lining and final finishes with instrumentation monitoring throughout.

Why Kubera for Tunneling

  • Geotechnical and structural engineering expertise for tunnel design support
  • Proven safety systems for underground works — ventilation, monitoring, emergency protocols
  • Experience in Himalayan and peninsular geologies
  • Quality-controlled shotcrete and lining works

Tunnel Construction — FAQs

What tunneling methods does Kuberagroup use?

We use TBM, NATM, drill-and-blast and cut-and-cover methods depending on geology, tunnel size and project requirements.

Do you build hydro tunnels for power projects?

Yes — we execute pressure tunnels, water conductor systems and penstock tunnels for hydroelectric projects.

How do you ensure safety during tunnel excavation?

We use continuous geological probing, instrumentation monitoring, controlled ventilation, shotcrete support cycles and strict permit-to-work systems.
