This chapter presents a review of studies on the performance of both natural and polymer-based geogrids and geocells as reinforcement in the foundation bed. An attempt was made to lay out identified research gaps and to present future directions for research to explore the potential of geocells made from natural materials. The performance of a variety of natural products, like areca leaf sheath, sisal leaf sheath, coir mat, and jute mat, as reinforcement was evaluated and compared with that of polymer-based geocells. A series of model footing plate load tests were conducted to evaluate the influence of different cell layers on the strength and stability behavior of the soil. Tests were performed on unreinforced soil as well as soil reinforced with areca leaf cells, sisal leaf cell, coir cell, jute cell, and polyethylene geocell for comparison. The settlement-bearing pressure behaviors were plotted, and it was observed that natural geocells perform at par with polyethylene geocells. The leaves and fibers can be chemically treated before application for extending its durability. |
