One of the areas your crawl space is getting moisture from is the ground. When you look at dirt, you can see there is a certain level of water content in it. What happens, when you don’t have anything protecting that crawl space from the ground, is that the natural water in the dirt is going to evaporate up into the air of the crawl space. A crawl space vapor barrier stops this from happening. It acts like a rain jacket for your crawl space.
In most South Eastern states like North Carolina and Tennessee, it is code to have a 6-mil vapor barrier completely covering the floor of the crawl space. Crawl Space Brothers installs from the code required 6-mil up to our fiber-reinforced 20-mil.
