1. Water leaks: One of the most obvious signs of a waterproofing problem is water leaks. If you notice water seeping into the building, it could be an indication of a failed waterproofing system.
  2. Mold and Mildew: If you notice mold and mildew growing in the building, it could be a sign of a waterproofing problem. Mold and mildew thrive in moist environments, so if you see them growing, it could be an indication of water infiltration.
  3. Peeling paint and damaged drywall: Water infiltration can cause paint to peel and drywall to become damaged. If you notice these issues, it’s important to investigate the cause, as it could be a sign of a waterproofing problem.
  4. Cracks in the concrete or walls: If you notice cracks in the concrete or walls of the building, it could be an indication of a waterproofing issue. Over time, water infiltration can cause concrete to expand and contract, leading to cracking.
  5. Flooring issues: If you notice uneven or sagging flooring, it could be a sign of a waterproofing problem. Water infiltration can cause the underlying concrete to weaken, leading to flooring issues.

It is important to address any waterproofing issues promptly, as they can lead to more serious problems such as structural damage, mold and mildew growth, and higher repair costs in the future.
