Over the past few decades, the scale of construction in Korea has grown rapidly. Therefore, the amount of sand and aggregate used in construction has also increased too. In order to satisfy of construction, the government permitted extraction of sand and aggregate. But river sand was nearly depleted and can get limited amount of sea sand. The case of sea sand because it contains a lot of salt, it has a significant impact on the durability of structure and the lifetime of the building. For this reason, the sea sand is not suitable as a material to fill the gas pipeline and water supply line. So the river sand of good quality is used.
In this study, permeability of water-repellent soil that can be used in back filling material when construction of underground pipelines were analyzed.
