Geocell is a three-dimensional cellular geosynthetic product to provide all-around confinement by theinteraction of infill soil, cell walls and cell geometry. This study comprises of laboratory model tests of geocell-reinforcedsandy soil with different dimensions of geocells to evaluate the amount of the contributions of the geocells with regards toheight of the cell, width of the cell and loading location. In addition, the load is applied at the center of the cell and at theintersection of polymer boundaries of geocells. Tests are conducted in a tank with dimensions of 1 m width, 1 m length andvarious heights depending on geocell height, where static loading is applied via a steel plate on the sand surface. The resultsare presented in terms of pressure-settlement plots. It is observed that for a predetermined settlement value, presence of thegeocells increased the bearing capacity of the footing by 38% to 73% compared to unreinforced cases and reduced thesettlements under a given pressure. Bearing capacity increased with increasing geocell height independently from geocellwidth. Decreasing of geocell width increased the bearing capacity of the footing independently from geocell height.
