15. Attractions of HVDM Save 30% in cost compared to conventional methods, leading to a total saving of US$5 billion. Shorten the construction period to 25-30 days via the pressure gradient, well less than the time required by conventional methods. Data acquisition throughout the treatment. Control the thickness of hard shell and treat sections independently, which meet the bearing capacity and settlement requirements. HVDM is a mechanical process, which adds no additions into the soil and protects the environments. 30% cost Saving 50% schedule saving QA/QC Environ-mental Safe

20. Schematic of Construction Hard Shell by HVDM Enhanced shaft friction

22. For shallow soft soil ， HVDM is used to form a over-consolidated shell. For deep soft soil ， preloading is used to consolidate the deep soil, and HVDM is then used to form a hard shell at the subsurface. For jobsite requiring high bearing capacity ， HVDM is used to increase bearing capacity. Stone columns are installed to form a composite foundation..
