Liner Plate Tunneling
Liner plate tunneling is a sequential excavation method used to construct tunnels in areas where surface disruption, limited access, or ground conditions make open-cut installation impractical. CRS Contractors performs liner plate tunneling for utility and infrastructure crossings that require controlled excavation and continuous ground support throughout construction.
When It’s Used
Liner plate tunneling is commonly selected for:
- Crossings beneath active roadways, rail corridors, or developed areas
- Installations in constrained sites where open-cut excavation is not feasible
- Projects requiring tunnel support as excavation advances through variable ground conditions
Our Approach
CRS Contractors evaluates subsurface conditions, loading above the tunnel, shaft access, and alignment requirements early in project planning. The company sequences excavation and liner plate installation to maintain support at the face and along the tunnel as work progresses, helping reduce settlement risk and maintain control in sensitive or heavily constrained environments.
