Countermeasures against landslide and slope collapse

Based on our extensive knowledge and experience of geology and ground, we propose investigation/design of restoration works and preventive measures.

Support sediment disaster prevention, countermeasures, and recovery

Japan’s land is extremely fragile because of repeated crustal movements, as well as many earthquakes and active volcanic activities. Sediment disasters occur frequently due to the weather conditions such as warm temperate and heavy rain. There are many seep slope areas in danger of collapse and hazard areas of landslide and debris flow throughout Japan.

The collapse of slopes is caused by many factors, such as groundwater rises due to rainfall, earthquakes, topography, geology, and vegetation. Therefore, in order to prevent disasters due to slope collapse, it is important to identify the mechanism leading to the collapse, to implement disaster prevention measures, and to grasp the various risk of the region in advance.
