We have been researching about cave-ins and sinkholes for many years.

For example,

• research of growth progress of cave-ins caused by ground water level changes or earthquakes
• creation of cavity potential map based on timing of infrastructure production and geological information
• development of filling materials for cavities and research on filling methods.
• research on methods for the exploration of deep cavities that are difficult to detect using existing methods.

We will keep working on these researches to eliminate the damage caused by ground cave-ins!
