However, temporary groundwater lowering (which consists of modifying flows in the ground generally for the purpose of carrying out an excavation) can cause numerous problems,<\/strong> even disasters, which are always expensive and can sometimes have dramatic consequences, due to:<\/p>\n\n- Inadequate surveying;<\/li>\n
- Incorrect design;<\/li>\n
- Hazardous construction choices;<\/li>\n
- Faulty execution;<\/li>\n
- A lack of monitoring during execution of the work;<\/li>\n
