Underground Infrastructure Repair

Underground infrastructure requires specialized repair approaches due to unique environmental challenges including hydrostatic pressure, limited access, and continuous operational demands. Our underground infrastructure repair service addresses the complex needs of subway systems, tunnels, basement facilities, and below-grade concrete structures.

Specialized Underground Applications

Our underground repair expertise includes:

• Subway and Transit Systems: Concrete repair in active transit tunnels and stations
• Utility Tunnels: Waterproofing and structural repair of underground utility corridors
• Basement Infrastructure: Commercial and industrial basement concrete repair
• Underground Parking: Comprehensive waterproofing for below-grade parking structures
• Storm Water Systems: Repair and sealing of underground drainage infrastructure

Challenging Underground Conditions

Underground environments present unique repair challenges:

• High hydrostatic pressure from surrounding groundwater
• Limited access requiring specialized equipment
• Contaminated groundwater and aggressive chemical exposure
• Temperature fluctuations and humidity variations
• Structural loading from surrounding soil and surface infrastructure

Advanced Injection Solutions

Our Euras Gel technology is specifically engineered for underground applications, providing:

• Pressure resistance up to 10 bar hydrostatic pressure
• Chemical resistance to groundwater contaminants
• Flexibility to accommodate structural movement
• Long-term durability in harsh underground environments

Minimal Disruption Methods

We understand that underground infrastructure often cannot be shut down for repairs. Our injection methods minimize disruption to ongoing operations while providing permanent structural protection.
