FIELD: building, particularly to consolidate frozen ground in thawed zone under building foundation.
SUBSTANCE: method involves driving injector in ground; injecting consolidation penetrative mix under pressure, which provides ground structure in weakened ground zones and ground compaction along compacted zone perimeter; following injector driving to create compacted zones adjacent above zones. The consolidation penetrative mix is cooled salt solution comprising filler of material having lesser heat conductivity in comparison with ground to be compacted.
EFFECT: extended field of method application, increased reliability and efficiency.
