Having a proper vapor barrier installed in your crawlspace with a waterproofing system can be the solution to various moisture-related problems. In addition, it is a cost-effective way to improve your crawlspace and prevent the need for any future repairs.
So, what exactly is a vapor barrier? A vapor barrier is a durable plastic liner like the one pictured on the right that is installed over the floors and walls of a crawl space. This vapor barrier prevents moisture from passing through the floors and walls. By preventing moisture from passing through, the vapor barrier keeps a crawlspace dry and protects the structure and insulation from any mold and or wood rot.
The best time to install a vapor barrier is when a crawlspace is being sealed with a waterproofing system. The vapor barrier will prevent the exterior moisture from entering the crawlspace, while the waterproofing system will capture any water seepage, transporting the water to a sump pump to be automatically ejected to the outside.
