Developing measure performance, especially in civil activities, is mainly based on economic or social approaches, regardless of its environmental effects. This matter has caused imbalances of human life and hazardous future for him. Modern human’s awareness of the imbalances in normal performance of the nature cycle, caused by technology, has led him to create some ideas such as sustainability and to consider its components in recent technology. This paper is to take the most appropriate soil improving and enhancing method out of the well-known ones, based on the sustainability framework (society, economy and environment). The methodology is descriptive-analytical. The data or questionnaire sheets were collected and the analysis hierarchical process (AHP) was used in order to achieve optimal analysis and determination of the best choice. The results showed that the soil stabling method is the most appropriate one among the existing methods of soil improvement and that it tends to show the most correspondence with sustainability principles. Regarding the results of this paper, all contractors and those who are involved in construction would be capable of choosing appropriate methods of increasing soil compaction and improving foundation loading, based on the sustainability indexes, which consequently causes remarkable decrease of the environmental damages for present and future generation.
