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.
HVDM is one of Geoharbour Construction Group’s series of patented technology, which outperforms dynamic compaction, one of traditional ground improvement methods. HVDM enables soil consolidation process expediated by a pressure gradient acted within the ground, which is formed between positive pressure (i.e., excess pore water pressure from dynamic compaction) and negative pressure (i.e., vacuum pumping). HVDM extends the treatment scope of dynamic compaction to saturated silty soil. By using HVDM, an over consolidated hard crust is formed in the subsurface, which helps mitigate the post-treatment settlement of a job site.
