Is a vapor barrier necessary?

If your crawl space has standing, excess water, then a vapor barrier is necessary. Vapor barriers prevent water from reaching building walls, ceilings, foundations, and more. The prevention of water vapor reduces water damage, foundation damage, and mold growth.

Our standard 20 Mil Vapor Barrier is great for small or temporary projects. With our product, you can reduce the water in your home. A reduction in water increases your home’s value and keeps your family safe.

How Do Vapor Barriers Help With Crawl Space Repair?

Vapor barriers are one of many solutions to waterproofing your crawl space. With a quality vapor barrier, you can seal your home and protect it from a long-list of potential problems and dangers.

An unsealed crawl space presents many dangers to your home. For example, without a proper barrier, water vapor can cause leaky walls. Leaky walls damage property foundations as well as lead to more humidity throughout your home. More moisture means less comfort as well as the potential of mold growth or furniture damage.
