Vacuum consolidation (or vacuum preloading) is a soft soil improvement method that has been successfully used by geotechnical engineers and specialists of ground improvement companies in countries such as Australia, China, Korea, Thailand and France for soil improvement or land reclamation. It does not necessarily require surcharge fill and vacuum loads of 80kPa or greater can, typically, be maintained for as long as required.
