The construction technique known as "Stone Columns." It employs hydraulic or electric vibroflot equipment combined
with a pressure chamber, generating 130kw of power and using air as a jetting fluid. This ensures optimal compaction and continuity of the
columns. Three drills and a crane are visible, excavating soil and injecting it underground to form columns. The diameter of these columns,
typically 30-50cm, depends on soil conditions. Each cycle involves vibration, compressed air jetting, and injection of granular backfill, raising
the column surface by 30cm incrementally until completion.
