For the appropriate design of large foundation deformation patterns of the reinforcement layers may to some extent permit the use of the results of small scale loading tests. This paper reports some of the small-scale model tests on reinforced sandy ground, which basically enunciates the various deformation pattern of the planar geocomposite reinforcement layer, subjected to static vertical loading. Initially load tests were carried out at three different relative densities (Dr=32%, 70%, 89%) from which optimum length (L) and placement depth of single geocomposite layer was found as 2.5B (B=footing width) and 0.4B respectively. After careful observation of the shape and deformation patterns of the reinforced zone, the same geocomposite layer was made into two possible shapes (V and channel shape). Load test results indicate that V-shape caused enormous increase in bearing capacity compared to plane layer.
