Open foundation vents were allowing the high humidity (water vapor) to enter the crawl space and take over. The pipes and duct work were falling victim to excessive condensation, while the thin vapor barrier was no longer protecting the area from ground moisture. The homeowners were ready to eliminate the moisture once and for all.
Tar Heel Basement Systems removed the old vapor barrier and sealed the open foundation vent. The CrawlSeal 20mil liner was installed along the entire crawl space floor and walls, ensuring no ground moisture or outside humidity could enter the space. The homeowners are already noticing their HVAC system working less, saving them money and the crawl space is now free of moisture.
