We can do that...

Whenever horizontal clearances cannot be maintained, or the depth of excavation is such that standard excavating equipment cannot be used, a vertical shaft may be the answer. Turn – Key Tunneling can perform vertical shafts from eight (8) feet in diameter to over fifty (50) feet in diameter. Vertical shafts can be used for manholes, pump stations, connections to deep sewers, foundations and other items requiring a deep excavation within a limited surface area.
There are several benefits associated with our vertical shafts. They include:
  • The depth of excavation is not limited to the reach capacity of a hydraulic excavator.
  • No piling is required, therefore any excessive vibration to existing structures is eliminated.
  • Shaft plates and reinforcing ribs allow us to grout the outside of the shaft so that no voids exist between the liner and the excavated soil.

A typical work shaft for our tunneling operations is limited to less than twenty-four feet in diameter. For design / build projects, our in-house Professional Engineer can custom design the appropriate shaft for your specific requirements.
