Amid the global shortage of construction sand and the crisis facing Vietnam’s construction industry with high-grade sand scheduled to run out in 2020, a factory on the island of Phu Quoc in southern Vietnam has opened to convert sea sand into construction sand.

In a process patented by Vietnamese engineer Vo Tan Dung in 2011, the beach sand is blasted with water to remove the salt and organic impurities before being refiltered. Tests by the Vietnam Institute for Building Science in March 2018 confirmed that the processed sand is suitable for construction.

The technique was licensed Phan Thanh Construction and the factory on the island just off the Cambodian coast is now able to produce 200 cubic metres of construction grade sand in just one hour.
