Precast Concrete Tunnel Liners

Precast Tunnel Segments are designed according to the tunnel geometry…

Our precast concrete segments are used in the construction of large diameter tunnels. The liners are installed in the field in a series of segments supporting the surrounding area. Concrete segments are used in a variety of applications such as transit, subways, rail, sewer and water projects.

Benefits of Precast Segments:

  • Thicknesses, length and radius are specifically designed to any tunnel requirements
  • Eliminates the need for secondary lining
  • Consistency and dimensional accuracy
  • More efficient and economical in comparison to conventional cast in place lining
  • Watertight Gasket
  • Suitable for soft and hard ground
  • Designed for 100 years of service life
