Tunnel & Shaft Secondary Lining

Once the primary support is established, secondary linings are installed to provide long-term durability and a finished internal surface. For tunnels, we manage all specialist resources from the pit top through to the face gang. For Shaft Secondary Lining, we employ specialist formwork techniques such as Slipform (a continuous pouring process) or Jumpform (climbing sections) to create reinforced internal walls.
