What we do

Our services include ground improvement, piling, deep excavation and marine construction works . For the ground improvement works, with patent technology HVDM and other traditional techniques, we are able to treat soil and sand at different conditions.

Our Services

High Vacuum Densification Method

High Vacuum Densification Method (HVDM), so called high-vacuum dewatering and dynamic compaction, is Shanghai Geoharbour owned patent. It is a soft soil improvement method that is fast and combines vacuum drainage and deep dynamic compaction in designated cycles, so that soils at the project site can be improved through the effects of lowered water content and increased density. This technology is most efficient in semi-permeable soil.
