Efficient Solutions for Sealing Tunnels
Groundworks specializes in tunnel sealing with polyurethane, designed to rehabilitate leaking tunnels by sealing cracks, stabilizing soils, and preventing groundwater migration. Perfect for transportation, industrial, or underground walkway tunnels, this process is fast, adaptable, and minimizes downtime.
Fast, Efficient Sealing for Tunnels
Groundworks’ tunnel sealing service with polyurethane is designed to stabilize soils, seal leaks, and prevent groundwater infiltration with minimal disruption. This process works for government, commercial, and industrial tunnels, delivering cost-effective and long-lasting results.
Polyurethane Injection for Tunnel Rehabilitation
Polyurethane is injected through the tunnel wall to target compromised areas, filling voids, stabilizing soils, and sealing leaky joints or cracks. This fast-curing grout curtain solution prevents groundwater from infiltrating tunnels, ensuring structural integrity and reducing future maintenance. Its adaptability makes it ideal for remote or high-traffic tunnel environments.
Indicators Your Tunnel Needs Sealing
Leaking or structurally compromised tunnels can lead to safety risks and operational disruptions. Watch for these key indicators to identify the need for sealing and stabilization.
- Visible Water Seepage: Groundwater entering through cracks or joints.
- Erosion or Voids Near Tunnel Walls: Loss of surrounding soil stability.
- Cracks in Tunnel Structure: Structural degradation impacting performance.
- Groundwater Migration Into Tunnel: Persistent moisture or water pooling in the tunnel.
- Settling or Sagging Tunnel Sections: Uneven surfaces caused by soil instability.
Benefits of Tunnel Sealing
Groundworks’ tunnel sealing service enhances safety, restores stability, and prevents water infiltration for critical infrastructure across government, commercial, and industrial sectors.
- Non-Invasive Installation: Injection through the tunnel wall avoids major excavation.
- Fast and Efficient Process: Reduces downtime and operational disruption.
- Improves Soil Stability: Fills voids and densifies soils around the tunnel structure.
- Prevents Groundwater Infiltration: Grout curtain blocks water migration into the tunnel.
- Versatile for Any Environment: Ideal for remote, high-traffic, or tight locations.

Products We Use
Polyurethane Injections
What We Do
We provide specialized solutions for tunnels, including stabilizing surrounding soils, sealing against groundwater infiltration, and filling voids with high-density polyurethane. Our methods enhance structural integrity, prevent erosion, and extend the tunnel’s lifespan.
How It Works
We inject high-density polyurethane into targeted areas around the tunnel. The expanding foam fills voids, stabilizes surrounding soil, and creates a water-resistant barrier, preventing groundwater infiltration and reinforcing structural integrity.
