Basement Waterproofing Options
Waterproofing a basement requires more than simply patching up trouble spots. Instead, it's important to not only locate the sources of the leak, but also to check for problems in the foundation of the home and prevent future leaks.
If you are already dealing with wetness in your basement, then start by locating the source of the moisture. This is best done by taping a piece of foil to the inside of the foundation wall. Let it sit for several days, then remove the foil to see if the wall or room side of the foil is wet. Both sides may have retained moisture and that means the problem lies on the inside and outside of the foundation.
If you notice moisture on the wall side of the foil, then it means the problem is making its way through the foundation. You may need to consult an expert about making exterior gutter and downspout repairs.
Interior basement waterproofing requires filling gaps with cement and sealing trouble spots with waterproof masonry paint. This will help to ensure basement waterproofing and prevent future problems.
