Precast Concrete Tunnels


Your Tunnel Sections Can Be Made, Stocked, and Ready to Go

Many colleges and universities trust Advance Concrete Products Co. to produce high quality precast concrete tunnel for their vast underground steam networks.  The tunnels shown here are stocked for Michigan State University.  They measure 5' wide x 3'-6" tall inside, are poured in requested lengths, and include hot-dipped galvanized steel weld plates cast-in during production for pipe support attachment. Even before the contractors have moved on site to excavate, we are manufacturing standard and custom precast concrete tunnel sections. When they call for delivery, Advance Concrete is ready!

Advance Concrete Products offers precast concrete tunnel systems for use in a wide variety of situations including: 

  • Steam Tunnel
  • Pedestrian Tunnel
  • Retention Chamber
  • Utility Tunnel
  • Culvert and Drain
  • Creek Overpass
  • Trench Drain
  • Conveyer Tunnel / Enclosure (shown above)


We have many different size options ranging from 2-6 wide all the way up to 36 wide.  If you are looking for a precast concrete tunnel with future access for equipment troubleshooting or maintenance, we manufacture a U shaped tunnel with a keyed precast concrete roof.  The roof slabs can be delivered later than the monolithically poured walls and floor, allowing you to install large steam lines or heavy duty hardware as your jobsite conditions allow.  Some customers prefer the precast concrete floor to be cast separately, with a monolithic, inverted style, top section to be set in our keyways.  Either way, Advance Concrete Products will build your precast concrete tunnel to your specifications. 


Hot-dipped, galvanized steel embedded weld plates can be cast in the walls, roof, and floor for your support and guide system.  Openings can be cast in walls during production for flow-through.  45 and 90 turns are ordered regularly.  We carry both cast iron frames and covers and aluminum hatches for roof access.  Your heavy duty tunnel will be manufactured to meet your jobsite loading conditions, from pedestrian to aircraft requirements.
