Engineering the Subsurface

Modern infrastructure demands safe and efficient underground solutions for transportation, utilities, and hydro projects. At Dogra Geomatics, we specialize in tunneling through complex Himalayan geology and other challenging formations, employing both conventional and mechanized techniques. Our expertise spans the entire project lifecycle - from geological risk assessment to final lining installation.

We understand that successful tunneling requires more than excavation; it demands comprehensive support systems tailored to ground conditions. Our team integrates advanced monitoring technologies with proven support methods to ensure structural integrity throughout the tunnel's service life.

Our Tunneling & Underground Support Capabilities

We deliver end-to-end solutions for underground construction challenges:

Tunneling Methods
  • Drill & Blast: Precision-controlled excavations in hard rock formations
  • Roadheader Tunneling: Mechanized cutting for medium-hard rock
  • Sequential Excavation Method (SEM): For unstable ground conditions
  • Pipe Roofing: Advanced pre-support for shallow tunnels
Support Systems
  • Rock Bolting: Systematic ground reinforcement using mechanical/grouted anchors
  • Shotcrete Linings: Fiber-reinforced sprayed concrete with accelerator additives
  • Steel Ribs & Lattice Girders: Heavy-duty support for high-stress zones
  • Forepoling: Preventive support ahead of the tunnel face
Specialized Applications
  • Cross-Passage Construction: Between parallel tunnels
  • Portal Stabilization: Slope reinforcement at tunnel entries/exits
  • Waterproofing Systems: Membrane installations and drainage layers
  • Final Linings: Cast-in-place concrete or precast segments
