Crawl Space Waterproofing Keeps More Than Just Water Out

Posted on: 4 December 2020

If you have a lot of water in your crawl space, then it makes sense that you would want to have your crawl space waterproofed. You can have the walls lined with plastic, have cracks and crevices sealed, and also have the floor poured with concrete or another impervious substance. As long as these processes are done properly, they should keep the water out. But that's not all that a good crawl space waterproofing job will keep out. Here are three other things it will keep away.


Mold loves moisture. In fact, most species of mold will only grow where it is moist. There are mold spores in the air everywhere, and as soon as they find a wet spot to land, they transform into adult mold and then replicate rapidly. It is very uncommon to have a wet crawl space that is not moldy. And when there is mold in your crawl space, there will soon be mold spores in the rest of your home. These spores can lead to symptoms from sneezing, to itching, to nausea.

If you have your crawl space waterproofed, then you can nix mold growth, too. This will make for a healthier home and easier breathing, especially for any family members with asthma or allergies.


Insects like cockroaches are big fans of a wet crawl space, as are ants, earwigs, and silverfish. You can spend months and thousands of dollars trying to exterminate these pests, but if the crawl space is still moist, they will just keep coming back. However, drying out the crawl space via waterproofing will keep these insects at bay. You might be able to stop relying on baits, insecticides, and other measures, too.


Some bacteria may not be overly infectious or dangerous, but they can still give off a nasty odor. Further, some of the bacteria could be infectious. If they find their way into an open wound or irritated patch of skin, you may end up with a boil or skin infection. However, waterproofing the crawl space and keeping it dry will keep these dangerous bacteria at bay. You will be able to spend time in your crawl space without having to wear gloves and long sleeves.

Waterproofing your crawl space does more than keep water out. It also keeps water-loving insects, mold, and bacteria out, which is very valuable. Contact a crawl space waterproofing company for more information.
