Foundation leaks can be a major issue for older buildings, as the aging materials and structures may not be able to withstand the elements as well as they used to. Here’s a guide to addressing foundation leaks in older buildings:

  1. Locate the source of the leak: Before you can address the foundation leak, you need to locate the source. This may involve digging into the ground to inspect the foundation, or using a moisture meter to detect water infiltration.
  2. Evaluate the damage: Once you have located the source of the leak, you need to evaluate the extent of the damage. This may involve removing damaged materials, such as drywall or insulation, and inspecting the structural components of the building.
  3. Repair the source of the leak: The next step is to repair the source of the leak. This may involve repairing cracks in the foundation, installing a new waterproofing membrane, or installing a new drainage system.
  4. Fix any structural damage: If the foundation leak has caused any structural damage, such as weakened beams or sagging flooring, it’s important to address this before moving on to the next step.
  5. Reinstall damaged materials: Finally, you will need to reinstall any damaged materials, such as drywall or insulation, and make any necessary cosmetic repairs to the building.

In addition to these steps, it’s important to consider other waterproofing and mitigation options around the entire building to prevent future leaks. This may involve installing a new waterproofing membrane, installing new gutters and downspouts, and addressing any grading issues that may be contributing to the problem.

Addressing foundation leaks in older buildings can be a complex and challenging process, but it’s important to address these issues promptly to prevent further damage and to keep the building safe and secure. If you’re unsure about how to address a foundation leak, it’s best to consult with a professional waterproofing contractor to get the best results.
