Crawl Space Encapsulation

A common method to control moisture in a crawl space is known as crawl space encapsulation. The term crawl space encapsulation relates to closing off the area under your house to prevent water and moisture damage. Many people refer to this type of work as a sealed crawlspace, but a more proper term would be a closed crawl space or crawl space encapsulation.

A proper crawl space encapsulation should look at controlling the three main sources of water under your house, which are ground water, ground moisture, and humidity. If you do not check each source, you may not address the root of the issue and end up spending more money in the future.



There are several reasons that a crawl space can have problems with moisture, and it takes an expert to find what is causing the problem. You don’t want someone to just show up and pull out a preformed solution for your home. In the end, you’ll want a crawl space specialist who can determine the exact problem and then design a system that will permanently solve the problem.



A common way for water to enter the home is through surface water penetration, which is when water begins to “pool up” and stand around your home. It can be caused by large amounts of water running off the roof, or just by poor yard grading. When water starts pooling up around your home like this, it becomes easier for it to find its way into your home through any weak spots.



Another common cause for water entering your crawl space is through something called groundwater penetration. Simply put, this is when the levels of moisture in the clay surrounding your home start to build up, leaving the excess water with no place to go except inside your home. The water usually comes in where the wall and the footer meet, then appears on the soil in the crawl space. This can saturate the soil, and in the worst cases, it will leave standing water throughout the crawl space.



The most common cause for moisture in your crawl space is something very simple: humidity. Even if actual liquid water isn’t leaking into your home through the causes listed above, it can still easily come in through the humid air. This can happen to any crawl space under the right (or wrong) conditions.
