Geocell reinforced foundation beds-past findings, present trends and future prospects: A state-of-the-art review

•Presented current state-of-the-art regarding geocells.•Reviewed past studies related to geocells.•Documented studies related to field performance of geocells.•Discussed future prospects of the geocells in geotechnical engineering.•Geocell found to be very promising ground reinforcement technique.

In the last few years, the use of geocell reinforcements in various infrastructural projects has gained importance due to its positive benefits. This paper reviews the developments and state-of-the-art pertinent to geocell research and field practices. The geocell studies covering, experimental, numerical, analytical and field performances have been reviewed. Characterization of the geocell has been discussed in detail. The field investigations of the test sections and the performance of the in-service geocell supported structures have been reviewed. A note has been presented on current research trends and the future prospects. A summary of the past research findings has been presented with a discussion on the research gaps in the subject area. It is evident from the past studies that the geocell is evolving as a promising sustainable ground reinforcement technique. Due to an increased use of geocells in the infrastructure projects, there exists an expansive scope for further research to understand the material better.
