Ground Exploration
Necessity of ground exploration
- In recent decades, there has been an increase in the construction of underground facilities due to urban development, fluctuations in groundwater levels, and damage to and leaks in aging water and sewage pipes. Due to soil leakage, underground cavities are formed and the number of urban road collapses is increasing.
- This increases the risk of damage to life and property and causes social unrest, which has emerged as a social cause at the central government level. Therefore, it is urgent to prepare underground joint detection measures to prevent this in advance.

Causes of intrusion and water leakage in old pipes
Water leaking from damaged water·sewer pipes forms waterways in the soil or soil flows into the pipes, resulting in dilated pupils and collapse·settlement of roads.
Occurrence cases
Most of the cases that occurred in Seoul were found to be due to damage to old water·sewer pipes.
