This method utilizes construction-generated soil as an alternative to natural sand, the conventional infilling material. Installing both construction-generated soil and artificial drainage material in the ground gives the same improvement effect as a conventional method. This is an environment-friendly ground improvement method that saves on natural resources and makes use of construction-generated soil which otherwise must be disposed of.
