It can be tempting to avoid waterproofing because it seems like a problem that only “certain crawl spaces” have. However, if you have any of the following things in your crawl space, it’s important to invest in waterproofing.
Dirt Crawl Spaces
If you have a dirt crawl space, there’s no way you’ll be able to make your crawl space completely free of moisture. Moisture in the earth goes down extremely far, and even if you’re able to dry out the top layer of moisture, it’s still going to come back up at some point.
Any homeowner with a dirt crawl space needs to make sure they’re laying down a crawl space vapor barrier. With a crawl space vapor barrier, all moisture from the earth stays on the outside of the vapor barrier rather than coming into the crawl space. From there, you can get to work on making sure your crawl space stays truly dry.
Crawl Space Vents
It’s common for people to have crawl space vents in their homes. For a long time, people felt like letting the crawl space “breathe” was crucial if you wanted to avoid crawl space moisture. To this extent, many new constructions had crawl space vents to allow for air circulation, and the process continues even today.
However, modern research shows that crawl space vents are much more trouble than they’re worth. Many crawl space experts now recommend that you cover your crawl space vents instead of letting them stay open. If you let your crawl space vents stay open, it’s very possible that you’ll end up with more crawl space moisture than if you were to close your crawl space vents and encapsulate the space entirely.
Leakage or Crawl Space Water
Of course, if you’re already experiencing water in your crawl space, you can’t just put in a dehumidifier and hope for the best. Standing crawl space water of any kind is bad for the crawl space because not only does it contribute to higher levels of humidity, but it can also cause water damage at any of the places that it touches the walls or the floor.
First off, to handle water leakage, it’s important that you fix any leaking pipes or condensation on the outside of pipes. However, if you’ve already done that, it’s possible that there’s some sort of deeper problem you’re not seeing. You may need to install a sump pump or some other method of removing water from the crawl space.
