Vibrocompaction: new record of depth

The largest onshore windmill with 7.5 MW is installed on top of an old brown coal dump area. A combination of vibrocompaction up to 68 m deep and additional stone columns 20 m deep were installed night and days.

This is a new record of depth and improvement quality in line with the stringent requirements of less than 4 cm differential settlement with up to 68 m of loose material above the natural soil.
