The new system allows 24-hour work with fewer workers.
In October 2026 Kajima announced it had automated foundation treatment for dams, the boring and grouting that seal the rock under a dam.
Reported gains
BUILT reported that the system allows 24-hour continuous work, about 50% more daily output, and up to 70% fewer workers per cycle. Nikkei xTECH reported that no resident monitoring staff are needed.
Why it matters
Kajima keeps pushing automation from earthmoving into the rest of the dam job.
