In recent year, the capacity of the disposal space of waste is running short. Accordingly, construction of new disposing site is needed.
The standard of impervious structure about a disposal site was defined by the law 1999. However, with the past technology about impervious sea wall, it is very difficult to construct this type of structure meeting this law. Then, we proposed new structure and material about impervious sea wall, which maintains the performance of water interception over long period. This research paper reports the result of the field experiment about impervioussea wall structure with clayey water interception material.
