ON DEMAND - Artificial Ground Freezing - An Unconventional and Environmentally Friendly Approach to Sealing and Containing Contaminated Soil and Groundwater

This event is available ON DEMAND

Artificial ground freezing (AGF) is a well-established method for managing groundwater during the construction of underground structures. Alternative applications include the use of ground freezing for the containment of impacted groundwater.

Key learnings and points covered

• Century-old technology for stabilising weak or unstable ground
• Flexible configurations and refrigerant options for ground stabilisation and groundwater containment
• Low CO2 footprint compared to a diaphragm or slurry wall
• Temporary structure that has no long-term effect on groundwater hydrology

Highlighting teachings and reason to attend

• Learn about potential environmental applications for groundwater containment or contaminant source control using AGF
