Soil Improvement - BAUER

Granular or weakly cohesive sediments such as gravel and sand often have very uneven layer densities in their natural state. With vibro-compaction densification (VCD) this can be increased to around 80 %. In the process, the soil is "floated" by a water or air flush, the vibrator sinks and a settlement depression is formed at ground level.
