Engineered Solutions for Complex Underground Structures

LJB Underground Services specializes in underground infrastructure, bringing unmatched tunneling, geotechnical and structural expertise to support projects from early planning and design to construction oversight. With 15+ years of experience on more than 100 tunneling projects worldwide, we have worked on some of the most challenging and important underground infrastructure projects in North America.

Where We Excel

Precision Under Pressure

We deliver high-quality underground and tunneling solutions even when timelines are tight, conditions are complex, and the stakes are high.

Boutique Expertise, Global Perspective

We combine the agility of a specialized team with the depth of international experience gained across Europe, North America, South America and beyond.

Bold Thinking for Complex Problems

When a tunnel, portal, shaft, or crossing requires something beyond standard practice, ours is the team people call.

Reliability Built on Relationships

Clients return again and again because of our consistency, honesty, and ability to support them through unpredictable situations.

Mining Services

Variable geology, ground control risk and production pressure leave little room for surprises underground. LJB’s mining team helps our partners understand the ground, manage risk and build infrastructure that performs for the life of the mine.

Mine geotechnical investigations: drilling programs, core logging, hydrogeology and instrumentation
Underground mapping and characterization: geologic mapping, LiDAR and reality capture, rock mass classification and ground models
Rock mechanics and ground control: stability analysis, support design and rehabilitation
Shafts, portals and mine infrastructure: excavation approach, temporary and permanent support, constructability
Risk, baseline and construction support: GBRs and GDRs, independent review, risk workshops and field engineering
Legacy mine risk and redevelopment: subsidence screening, mine stability and reuse planning
