The settlement of the Holocene clay layer ended during the construction of Kansai International Airport. We installed a million sand drains (20 m long and 40 cm in diameter) at 2.5 m-intervals into the clay layer under the main island and 1.2 million sand drains under the second island. The second runway opened on 2 August 2007, but with the originally planned terminal portion postponed. The airport was built on reclaimed land, and it is thought that the land is still settling.

For this reason, the structure is extremely water permeable. Roger Mola is the Air & Space researcher. This was done by injecting concrete into the ground beneath the runway. You can update your choices at any time in your settings. The settlement data of the Pleistocene clay layer, collected since construction started on the first island, shows that filling the sea does not have significant effect on the Pleistocene clay layer, as the weight of the island does not exceed the load-bearing capacity of the layer (buoyancy decreases the weight of sand).
