Tunnels

KWV Estates Infrastructure 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 KWV 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
