High Vacuum Densification Method(HVDM) was introduced to Hebei Caofeidian Industrial Park. Many construction sites of several hundreds of hectares, including tens of major roads, coal docks, railways, logistics, etc, were treated by using HVDM, thus saving billions of construction funds. On Feb. 15, 2009, CCTV News reported, the Innovative High Vacuum Densification Method(HVDM) Technique for soft ground improvement can solve the problem of soft ground reinforcement in reclamation engineering, save one-third of the cost and shorten the construction period by half compared with the traditional construction method.
