This paper presents the results of the 1-g model tests performed on geocell reinforced sand bed supporting the square footing. Plate load tests were conducted in a square shaped tank with 600mm depth and 900mm width to understand the behavior of the geocell reinforcement. New commercially available PRS Neoweb geocells made up of polyethylene were used in the investigation; which is known for its high strength and durability. Test results of unreinforced, geogrid reinforced, geocell reinforced, and geocell with additional planar geogrid have been compared. Results show that the provision of geocell increases the ultimate bearing capacity of the sand bed by 4 times. Introduction of planar geogrid at the base of the geocell mattress further enhances the performance of the footing by increasing the load carrying capacity, arresting the surface heave and preventing the footing rotation.
