The major problem with this crawl space vent system is that there is little to protect against outside influences. When air is allowed to come in the crawl space in susceptible to a myriad of problems. If hot air comes in, the hot air is cooled and turns into condensation making the perfect damp space, ideal for breeding ground for mold and creepy crawlies. If cold air is let in, the cold air will rise from the bottom to the top, meaning those heat generating utilities will have to work that much harder making for a heftier utility bills.
The crawl space before encapsulation reveals exposed earth, perfect situation to allow radon to seep in from the ground and circulate through out the house making the home hazardous for the occupants.
This crawl space after encapsulation is sealed and protected from the earth. The space is brighter making it a little more comfortable to access if the homeowner should need to enter the space for any reason. The space is kept dry with installation of the SaniDry CX (partially pictured on the right of photo) is designed specifically for small spaces to both filter and dehumidify the air all in one unit. An added bonus is that there is no dumping involved! The SaniDry CX will drain to the local sump pump or drainage system.
The SmartDrain (pictured on lower right of the photo) is a great choice for crawl spaces that have pipes running through the space. In the case of a leaking pipe for example, the homeowner has the SmartDrain to drain away water. The SmartDrain comes with the WaterWatch alarm that will alert the homeowner of a water problem in the crawl space that needs their attention.
Now that the crawl space is encapsulated and insulated, the homeowner needs to make sure it stays that way be sealing off the vent. A snug-fitting, all plastic door will stop air and moisture from entering the crawl space.

Crawl Space Encapsulation in Moline, IL

Mike is the homeowner of this rather small crawl space in Moline. He wanted to insulate and encapsulate the space so he called the experts at MidAmerica Basement Systems. True to form, there is no job too big or, in this scenario, too small that MidAmerica will not try to resolve. The team encapsulated the space with the strong, long lasting and mold resistant CleanSpace. With pipes running through the space, leaks may be inevitable. For this reason, the team installed the SmartDrain, specially designed for crawl spaces to drain water out of the space. To further seal the space from outside influences, the team sealed the vent with an inorganic and durable vent cover. Though tiny, this crawl space is cleaner, dryer and protected.
