About Ground Freezing

Artificial ground freezing is a construction technique that is used in the construction of shafts, mines and tunnels to provide temporary ground support and groundwater control when other conventional methods such as dewatering, shoring and grouting or soil mixing are not feasible.

Ground freezing is a versatile construction technique used to temporarily solidify the ground. By inserting pipes and circulating a cold brine or refrigerant, heat is extracted from the soil, causing it to freeze and form a solid mass. This technique is invaluable in challenging conditions, such as in soft ground or the presence of groundwater.

Presentation

• Ground freezing principles and applications
• Ground characterisation and laboratory testing for ground freezing design
• In situ monitoring during construction
• Project examples from various countries

Speaker

Michael Löffler, a leading expert in ground freezing, heads the group at CDM Smith (Germany) specialising in this technique. His projects include the cross passages at the Silvertown and High Speed 2 tunnels in London, the tunnels under the Suez Canal in Ismailia (Egypt), the new construction of the federal intelligence service building in Berlin, the North-South metro line in Cologne and the Post Tower high-rise in Bonn.
