I am a self-taught artist, initially drawn to experiment with pastels and colored pencil, and now working with acrylic on canvas. My art speaks for itself.

Basement Waterproofing questions, answered by experts

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

Water damage always poses the risk of mold, but if you act quickly enough (within the first 24 hours), you may be able to avoid mold growth resulting from water damage. Clean up the water quickly and thoroughly dry the area. If the issue is more extensive or you didn’t act quickly enough, it’s always safer to assume mold has grown and hire a mold inspector to examine the area.

The easiest methods for waterproofing your basement include installing a gutter system to direct excess runoff away from your foundation and grading the soil away from your home to pull water away from the concrete. In some cases, these methods alone can be enough to eliminate water intrusion and moisture problems in your basement. If you have excessive rainfall in your area, though, you might need to employ more complicated solutions, like installing a French drain and a dehumidification system inside.

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.
