A pilot test on a membraneless vacuum preloading method [PDF]
Geotextiles and Geomembranes, 2017 Abstract A membraneless vacuum preloading method is proposed in this paper for soft soil improvement. The method offers several advantages over the conventional vacuum preloading in which membrane is used to create the airtight condition and sand blanket layer to distribute vacuum.

Sustainability of Combined Vacuum and Surcharge Preloading [PDF]
Geo-Congress 2014 Technical Papers, 2014 This paper presents a review of combined vacuum consolidation and surcharge preloading which is arguably more sustainable approach to soft-soil ground improvement than other strategies in reducing post-construction settlements. Vacuum consolidation has become more prevalent with technological developments in vertical drains, pumps and geosynthetics ...
