Why Waterproof?
High relative humidity causes numerous problems. There are a few preventable causes of high relative humidity:
- Leaking groundwater through your crawl space walls.
- Exposed earth on the floor of the crawl space.
- Open vents to the outside.
A damp environment is very unhealthy and destructive. Mold thrives and reproduces by producing airborne spores by the millions, and some molds are toxic. Insects and critters of all kinds love damp environments and wet materials. Rot and decay occur in damp environments causing structural damage.
Mold spores, odors, humidity and critters create a very unhealthy environment for people to live in. Many people are allergic to these things, and experience a host of symptoms and don't realize that their dirt crawl space is affecting their health.
