What Is the Encapsulation Process?

Installing vent covers over any open ventilation within your crawl space is just one part of an entire crawl space protection process known as encapsulation. There are quite a few steps to this process that work together to keep this important space dry. 

• Drainage Systems, Sump Pumps, and Vapor Barriers 

The first step of the encapsulation process is to drain out any standing water or sewage from your crawl space. It does not make sense to seal off a space that is still full of moisture, right? Experts may install a drainage system with a sump pump to accomplish this. This system will collect and redirect any water that seeps through away from this space so it will stay dry. This water is typically directed out to a more appropriate drainage site, or may even be distributed out onto your lawn. 

They will then install a vapor barrier on the crawl space floor and walls. This will ensure the soil will not absorb too much moisture and weigh down on your foundation. Too much weight will likely cause the foundation to shift or crack, leading to a slew of other infrastructural issues. 

• Vent Covers and Dehumidifiers 

The last two steps involve installing vent covers over any open ventilation and a dehumidifier. Closing off the crawl space from any outside air is important, of course. Over time, however, the air trapped within this space is likely to become stale and even rot the crawl space from within. This is where a good dehumidifier comes in. It can easily cycle out stale air for fresher, dry air. 

Of course, homes dwelling within drier climates will not need to install every step of this process. A crawl space expert might deem installing vent covers and a trusty dehumidifier to be enough in this case. Either way, these last two steps are crucial components to keeping your crawl space dry.
