If you have water collecting in crawlspace and concrete walls in your crawlspace, then you’re experiencing a common problem. The ventilation openings were designed to flush out moisture from crawlspaces, but they often don’t do the job, except in dry climates. 
In fact, during humid summer conditions, they often make matters worse. The humid air carries moisture that condenses on the cool walls, the pipes and even the underside of floors witch creates a big problem that will cost THOUSANDS.
The best solution is to install a vapor barrier inside the crawlspace and encapsulate the structure to prevent microbial mold growth from eating away at your structure
