Hybrid Sealed Crawl Space

Hybrid Sealed Crawl Space

Our Hybrid Sealed Crawl Space System is installed to control high humidity issues. It is our more basic sealed crawl space system which includes a 6-mil poly liner, sealed crawls space vents and a dehumidifier. We typically recommend the GreenSpace Sealed Crawl Space System, our ultimate system, however in certain circumstances only the hybrid is needed.

Step 1: Seal Seams of Vapor Barrier

A 6-mil moisture barrier is placed over the crawl space floor and sealed to help reduce moisture from the ground rising up into your floor system, insulation, and home. We recommend 100% of the crawl space floor be covered with at least a 6-mil poly as stated in the current NC building code.

(Our Greenspace Sealed Crawl Space has a thicker, more durable 20-mil poly which is installed along the interior crawl space walls, around the interior crawl space piers, and over 100% of the crawl space floor.)


Step 2: Seal Crawl Space Vents

The next step in sealing a crawl space is ensuring no humid outside air is getting into your crawl space. We seal your vents with an insulating board to avoid hot or cold spots into your crawl space.


Step 3: Install Energy Star DeHumidifier

A dehumidifier is an essential step in a crawl space encapsulation, which is why Moisture Loc uses dehumidifiers that are designed specifically for crawl space or basement application’s. The Santa-Fe Dehumidifier is placed into the crawl space in order to dry out humid air and keep moisture away.

The dehumidifier is equipped with a fan that draws in moist, humid air through a cold evaporator coil, cooling the air below its dew point. Once the air is cooled below dew point, it turns into water, which is collected and automatically drained.

We can ensure your sealed crawl space will be installed properly, however over time outside factors can impede its performance.
