Abstract: Pond ash is waste by product which is producing in huge quantity by thermal power plants. The disposal of pond ash is the major problem to the environment. The way for disposing pond ash would be as a structural fill for low lying areas and used as embankment material. In this paper laboratory investigations are carried out to improve the bearing capacity of pond ash reinforced with geo-grid by conducting load tests in a model tank. The parameters varied during the tests were number of reinforcement layers and overlapping of reinforcement. The improvement of ultimate bearing capacity is observed. The ultimate bearing capacity ratios were evaluated
