The execution of large-scale soil improvement works across the GCC has provided critical insights into the complexities of working with challenging geotechnical conditions in arid and coastal environments. One key lesson is the importance of tailoring improvement techniques, such as roller compaction, dynamic compaction, vibro-compaction, vibro-replacement and deep soil mixing, to site-specific soil profiles and conditions.

Understanding relative density is essential when it comes to soil densification, particularly for cohesionless soils as it helps engineers make informed decisions about the need for densification and the methods required to achieve the desired soil stability for construction projects.
