Specialty drilling is typically required for applications other than deep foundations elements or ground improvement to create room for installation of utilities, ventilation or to provide access. 

Common Uses

  • Ventilation
  • Installation of utilities
  • Provide access

Technical Details

Specialty drilling is typically performed when conventional excavation techniques are not feasible to provide access to existing utilities or infrastructure. Multiple or modified drilling processes are usually adopted to perform specialty drilling. Many specialty drilling applications are performed in restricted access environments such as low headroom conditions, limited working areas, limited clearances from existing utilities and low tolerances for deviation.
