Trenchless Services
Tunneling
Tight-tolerance, long-distance grade requirements with unparalleled accuracy. Experienced crews and state-of-the-art equipment.
The Process
Ground Support & Liner Installation
The tunneling process begins by establishing a ground support system (liner) to enable product pipe installation.
The liner is constructed during tunnel construction using either steel casing or concrete tunnel liner plates, providing structural integrity throughout the excavation.
Scale & Expertise
Moving Mountains Underground
From transit infrastructure to major utility corridors, our tunneling operations have constructed passages up to 12 feet in diameter, moving thousands of cubic yards of material while maintaining rigorous safety standards in challenging ground conditions.
