A crawl space vapor barrier is a durable plastic sheet that covers crawl space walls and floors. 

It’s key to controlling moisture and blocking water vapor from entering the space. Vapor barriers combat mold, rot, and pests. 

Foundation Recovery Systems uses the robust CrawlSeal™, a multi-layered liner that effectively protects your home from moisture damage. Combined with our encapsulation process, it ensures your crawl space remains clean and dry even with our unpredictable climate.
