Soft ground improvement construction method

Prefabricated Vertical drain method (also known as PVD method)

After installing the prefabricated vertical drain material in the soft clay ground, by preloading, the water inside the soft soil can be drained out, therefore achieving the consolidation settlement. The water is discharged through the sand blanket (high quality sand) out of the area. This method is to prevent future land subsidence.

  • The sand blanket is not necessary
  • Reduce consolidation delays
  • Simple and secure constructions

Furthermore (What’s more)

  • Reduce cost and construction period
  • Reduce the amount of sand usage
  • Prevent slip failures of the embankment
