Foundations are built to transfer structural loads to the ground without load-bearing-capacity and settlement failures. If the soil conditions are favorable, shallow foundations are usually recommended but in case of weak ground conditions, deep foundations are essentially required. Use of geosynthetic reinforcement within the foundation soils is one of the cost-effective options to avoid construction of expensive deep foundations. The presence of geosynthetic layers reduces the settlement and enhances the load-bearing capacity of the soil mass. The simplicity of the basic principles and the economic benefits over the conventional approaches make geosynthetic-reinforced foundation soils very attractive to designers. In view of these advantages, researchers have carried out many analytical, numerical and experimental studies of the load-bearing capacity behaviour of geosynthetic-reinforced foundation soils. However, there is still a research scope for further development of this subject in order to consider some practical aspects which have not been given due attention. Therefore, this paper presents a critical review of the past developments aiming at clearly defining the key field requirements and performance factors for further consideration by the researchers.
