This paper presents the results of a laboratory investigation on construction method of geogrid encased stone column (GESC). In order to analyze effects of load carrying capacity and geogrid deformation characteristics of GESC, a series of medium scale unconfined compression tests with different overlay methods and reduced model tests were performed. The test results show that the method of overlap provides a simple and effective method of encasement construction. It is also found that geogrid encasement construction using method of overlap has important factor which can be applied to field tests. The geogrid encasement method related to effect of reinforcement is presented by laboratory test results.
