Infrastructure has become a major force for national development. Therefore, the development of ground improvement technology for weak subgrade composition has become an important goal in geotechnical engineering applications. Geosynthetics is one of the ground improvement techniques to improve bearing capacity of problematic subgrade soil. Geocell, the cell matrix expands to create radial stress and provide stability to the subgrade composition soil. In the past few years, the use of geocells and other methods to improve the properties of problematic soil, especially in pavement and foundation engineering, has been investigated. This paper focuses on presenting parameters such as increased bearing capacity, decreased settlement and increased stiffness when reinforcing various types of collapsible soils by addressing laboratory tests and field investigations for geocell configuration and highlights their advantages in various applications and future research. Research shows that geocells can improve the properties of problematic subgrade soil, making it suitable for many engineering applications.
