Planning: Based on the findings, a waterproofing plan will be designed. 3. Implementation: Techniques like installing interior drains, exterior barriers, or sump pumps will be carried out. 4. Assessment: After installation, the system will be evaluated to ensure it works effectively. The whole process can take anywhere from a few days to a week.
