Additional candidates for ground freezing include:

  • Circular or elliptical, open excavations, such as might be required for pump stations and other large structures.
  • Containment of contamination.  Installation of a frozen perimeter zone around the contaminated soils allows excavation and removal without permanently impacting the surrounding groundwater regime.
  • Fast acting liquid nitrogen can be used to stabilize loose or disturbed soils above a mired or damaged TBM for retrieval or repair.
