artificial freezing

artificial freezing

artificial freezing Method of controlling groundwater and improving strength of ground by pumping a refrigerant, e.g. calcium chloride or liquid nitrogen, through tubes in the ground; as the ground freezes around closely spaced tubes, a continuous frozen zone may be formed. This is an expensive technique, but suitable for mixed strata as the results are more predictable than dewatering or grouting.
