Abstract: The rapid growth of the big cities in the vertical direction leads to essentially of strengthening of low bearing capacity areas as the cost of land is very high and also, the disposal of the plastic wastes such as plastic bottles, bags etc. is a big problem and environmental hazards in such areas. The waste plastic bottles as geotechnical material are used to solve both geotechnical and environmental problems. The laboratory investigations are carried out to evaluate the effect of waste plastic bottles as soil reinforcement for improving bearing capacity of soil. The bearing capacity of square footing on sandy soil reinforced with waste plastic water bottles for different L/D ratio, number of layers and for different densities of foundation soil is evaluated through model test. The increase in the bearing capacity with the provision of waste plastic bottle as reinforcement is observed.
