High Vacuum Densification Method (HVDM)

 High Vacuum Densification Method (HVDM) is an advanced method for improving the physical properties of materials. It involves the application of high vacuum pressure to a material in order to decrease its porosity and increase its density.

About High Vacuum Densification Method (HVDM) 

  • One of Geoharbour group’s patented technologies
  • Suitable to improve soil that has fines content with a high ground-water table, such as silty sand and clayey sand
  • The combination of vacuum drainage (- pressure) and dynamic compaction (+ pressure)
  • Effectively dissipates excess pore water pressure
  • Improve the soil through the effects of
