Tunnel & Underground Infrastructure Solutions
URETEK provides trenchless polymer injection and waterproofing solutions to support, seal, and stabilize tunnels, vaults, buried utilities, and other underground infrastructure. Our non-invasive systems are designed to mitigate infiltration, voids, and settlement—extending the service life of subsurface structures while minimizing disruption to critical operations
Underground Infrastructure We Support
Transit, Subway, and Utility Tunnels.
Underground Vaults and Pump Stations.
Stormwater and Sanitary Sewer Pipelines .
Jack-and-Bore and Microtunnel Launch Zones.
Duct Banks and Utility Conduits.
Cut-and-Cover or Mined Tunnel Interfaces.
Subsurface Challenges We Solve
Groundwater infiltration through joints, liners, or cracks.
Voids caused by erosion, washout, or tunneling activity.
Loss of ground support beneath vaults, ducts, or conduits.
Soil instability around launch shafts or below-grade access points.
Chemical degradation or hydrostatic pressure near tunnel linings.
URETEK Underground Solutions
Curtain Grouting: Forms watertight barriers behind tunnel liners and walls.
Void Filling: Restores support beneath and around underground structures.
Permeation Grouting: Increases cohesion and stability in weak soils.
Deep Injection®: Compacts subgrades and improves load transfer.
Joint & Crack Sealing: Prevents infiltration in pipes, vaults, and tunnel segments.
Advantages for Tunnel and Utility Owners
Confined-space compatible—access through small ports or galleries .
Fast-curing materials resist water, pressure, and chemical attack.
Ideal for rehabilitation, maintenance, or pre-construction ground improvement.
Non-disruptive to aboveground structures or operations.
Proven across municipal, industrial, and DOT tunnel systems.
Use Cases
Sealing infiltration in sanitary sewer or stormwater tunnels.
Stabilizing launch zones for microtunneling or jack-and-bore.
Supporting aging underground vaults in urban environments.
Emergency remediation of erosion beneath buried infrastructure.
Waterproofing cut-and-cover tunnel joints or connections.
