A series of the experimental testing program was carried out to determine the influence of cell geometry and multi-layer system on the behaviour of a square footing resting on geocell reinforced sand. Geocells made of three different PVC polymers of varying thickness and strength were used for testing purpose. Laboratory plate load tests were conducted to determine the pressure–settlement response of reinforced soil for different geometric parameters like diameter, height, depth of placement, and shape of the geocell. The effect of geocell material strength on load carrying capacity is also included in this paper. Performance comparison of single layer and multi-layer geocell reinforced sand with different spacing is also presented in this paper. The test results confirm that the reinforced sand layer shows an excellent improvement in bearing capacity in comparison with the unreinforced sand. The optimum geocell geometry to get maximum benefit in terms of bearing capacity were determined and presented in this paper. Optimum spacing for a two layer geocell system was also determined experimentally and presented in this paper.
