This paper presents soil improvement method of loose fine sand soil in the deep desert area of an arid Central Asia country for the natural gas facility expansion project. The proposed site required a very deep treatment depth. In addition to dynamic compaction and other conventional local available soil improvement methods for the arid fine sandy soils, the water submerging method was introduced in this project. The results of the water submerging method treatment at the proposed site was examined by the late loading tests, standard penetration tests and heavy dynamic cone penetration tests. The test results of all three methods showed that the soil improvement method as acceptable and it is concluded that the water submerging method was successful in treating the arid fine sandy soils.
