WAYS MOISTURE ENTERS A VENTED CRAWL SPACE

MOISTURE AND STRUCTURAL ISSUES
You’ve probably heard that moisture is the number one cause of structural failure in homes. Well, you’re right, but this problem can be easily fixed by sealing off your crawl space. In this article, we’ll explain to you what needs to happen if you must keep any water out of your home:
Moisture can enter a crawl space through the ground, foundation, floor, and walls. It is because the soil humidity infiltrates your home via cracks in foundations or floors and other areas where water has leaked through to the ground level. If this moisture settles on top of the crawl space floorboards or insulation, it can lead to mold growth over time.
FOUNDATIONS
The foundation is a moisture barrier and can be a source of problems in the crawl space. Foundation vents allow air to circulate through the basement, so these openings should be sealed with weather-stripping or rubber gaskets. Make sure your foundation vents are located at least four feet above grade and sloped toward the outside of your home (away from any walls).
Wood framing expands and contracts with changing temperatures and seasons, creating cracks that allow moisture to enter the crawl space. The cracks can also cause air leaks through the wall voids, which may be as small as 1/8″ wide or larger.
FINALLY, SEAL YOUR CRAWL SPACE
The best way to stop water from entering your crawl space is by sealing it with professional services in crawlspace waterproofing in Charlotte, NC. Sealing the crawl space will keep it dry and prevent mold from growing, which can be harmful if left unchecked. When installing a vapor barrier or other material into your crawl space, check if the seams are sealed tight so no moisture can seep through cracks or gaps in the wall.
You should also consider adding an elevated foundation above ground level (1-2 feet) if possible; this will help direct any water away from where it enters your home and into its own drainage system rather than pooling on top of the floorboards below.
