Tunnels & Underground Services provide structural rehabilitation, protection, and long-term durability for subsurface infrastructure. Using specialized shotcrete, concrete repair, and lining systems, this service strengthens aging tunnels, stabilizes underground environments, and restores critical pathways without major disruption.

Whether addressing deterioration, water intrusion, structural cracking, or full-surface rebuilding, underground work requires precision and materials engineered for extreme environments. Shotcrete and advanced lining systems allow crews to rebuild surfaces quickly and safely, even in confined spaces or high-moisture conditions.

Key Benefits:

• Structural reinforcement for aging or damaged tunnel walls and ceilings

• Shotcrete application for fast, high-strength resurfacing

• Waterproofing and leak control using membranes, coatings, or specialty linings

• Corrosion protection against moisture, chemicals, and groundwater exposure

• Minimal disruption to traffic, utilities, and operations

• Compatible with transportation, utility, mining, and municipal systems

Typical Applications:

• Transportation tunnels (road, rail, pedestrian)

• Utility and sewer tunnels

• Underground stormwater systems

• Mining passages and shafts

• Pump stations and underground vaults

• Culverts and large-diameter pipelines

From structural repair to full-surface rehabilitation, Tunnels & Underground Services ensure safer, stronger, and longer-lasting underground infrastructure.
