Geosynthetic are used for reinforcements in many problem areas of civil engineering. It is mainly used to improve the bearing capacity and reduce settlement of the soil. Geogrids, geocells and geotextile are commonly provided as soil reinforcement which improves the bearing capacity and reduces settlement of foundation. The bearing capacity of square footing on sand reinforced with single layer geotextile reinforcement at different dimensions with cement interface is studied. A cement interface zone is created on the surface of geotextile to improve the friction and adhesion of sand and geotextile. Tests are also conducted on reinforced soil without cement interface and the results are compared to find out the variation on bearing capacity. Cement treated interface improves the bearing capacity and reduces the settlement. From the literatures referred depth and dimension of reinforcement affect the bearing capacity of the reinforcement. Test on unreinforced sand, reinforced sand and reinforced sand with cement interface of size 20cm, 25cm and 30cm geotextile at 0.5B depth from the base of footing. The result shows that size of the geotextile increase the bearing capacity considerably in both cases. When ordinary geotextile was treated with cement interface 10% to 40% increase in bearing capacity was observed. The cement treated geotextile improves the bearing capacity at lower size than ordinary geotextile.
