Tunnels/Trenchless  
While most pipe systems are installed using open-cut construction, some projects require that pipe be installed using trenchless methods. Concrete pipe is the ideal trenchless product due to its strength, rigidity and durability.

For instances where the tunnel diameter is larger than can be precast as a unit, Hanson produces segments that are assembled into a circular ring of the appropriate diameter.

Either way, Hanson has the ideal product for your trenchless job.
