Aging or Damaged Tunnels & Underground Spaces
If you're responsible for an old tunnel, culvert, or other underground space showing signs of wear, leaks, or instability, it's time for expert attention. We specialize in rehabilitating and reinforcing these vital underground structures.
Understanding Aging or Damaged Tunnels & Underground Spaces
Underground infrastructure—tunnels, culverts, mine portals, and utility corridors—often operates out of sight and out of mind until problems become critical. Aging liners, water infiltration, ground movement, and deteriorating support systems can compromise these vital structures. Rock Supremacy brings specialized expertise in tunnel rehabilitation, combining rope-access capabilities with shotcrete, rock bolting, and ground stabilization to restore structural integrity and extend service life.
Does This Sound Familiar?
"The concrete liner in our tunnel is spalling and cracking, with pieces falling onto the roadway or tracks. We need to restore structural integrity without extended closures."
We remove deteriorated concrete, install supplemental rock bolts to reinforce the surrounding ground, and apply new structural shotcrete lining. Our methods minimize closure time while delivering long-lasting repairs.
"Water is leaking through our tunnel walls and ceiling, causing ice buildup in winter and accelerating deterioration. Standard waterproofing hasn't worked."
We identify water pathways using specialized techniques, then apply targeted grouting to seal them at the source. Combined with drainage systems, we manage groundwater to keep your tunnel dry and extend its service life.
"Loose rock is falling from the crown of our unlined tunnel, creating safety hazards and operational concerns. We need to stabilize the rock mass without installing a full liner."
Our rope-access technicians scale loose material and install pattern rock bolts with mesh or shotcrete to create a stable rock shell. This cost-effective approach addresses immediate hazards while providing long-term stability.
How Rock Supremacy Solves Aging or
We utilize a range of proven geotechnical services, expertly applied to solve your specific challenges. Our methods are designed for maximum safety, durability, and project efficiency.
Tunnel Rehabilitation
Complete assessment and restoration of tunnel linings, including removal of deteriorated material, reinforcement, and application of new structural shotcrete.
Rock Bolting
Installing systematic patterns of rock bolts to knit together fractured rock masses and provide structural support for tunnel crowns and walls.

Shotcrete Application
Spraying structural concrete onto tunnel surfaces to create new linings, repair deteriorated concrete, or provide immediate support for unstable ground.
Learn More
Pressure Grouting
Injecting grout behind tunnel liners to fill voids, restore contact with surrounding rock, and seal water pathways that cause leakage and deterioration.
Learn More
Rock Scaling
Removing loose and hazardous rock from tunnel surfaces using manual and mechanical methods, performed by certified rope-access technicians.
Learn More
Geotechnical Drilling
Precision drilling for rock bolts, drain holes, and investigation of ground conditions behind tunnel linings to inform rehabilitation design.
Learn MoreCutting-Edge Equipment & Expertise
Successfully tackling complex ground challenges demands precision, power, and innovative tools. Rock Supremacy leverages advanced technology to ensure the safest, most efficient, and durable solutions.
Rope Access Expertise
Our trained technicians can work anywhere in a tunnel environment without scaffolding or heavy equipment, reducing costs and closure times.
Mobile Shotcrete Systems
Self-contained shotcrete rigs that can operate within tunnel confines, delivering high-strength structural concrete precisely where needed.
Ground-Penetrating Radar
Non-destructive scanning to identify voids behind liners, assess liner thickness, and detect deterioration before it becomes visible.
Convergence Monitoring
Precision instruments that track tunnel movement during and after rehabilitation, ensuring stability and validating repair effectiveness.
